Below are the articles which can help with the configuration: There are two types of failover that can occur when Active/Active Clustering is enabled: High Availability failover Within an HA pair, the Secondary unit takes over for the Primary. In general, any network advertised by one node will be advertised by all other nodes. "Client IP and protocol" specifies that successive requests from the same client IP address and protocol combination will be handled by the same virtual machine. 6. illustrates the Active/Active Clustering topology. Active/Standby HA provides the following benefits: Increased network reliability In a High Availability configuration, the Secondary appliance assumes all network responsibilities when the Primary unit fails, ensuring a reliable connection between the protected network and the Internet. 4. In a deployment with two Cluster Nodes, the X0 Virtual Group 1 IP address can be one gateway and the X0 Virtual Group 2 IP address can be another gateway. Physically connect the designated HA ports from the Primary to the Secondary HA unit. The two ports must be physically connected to the same switch, or preferably, to redundant switches in the network. 16. Navigate to the left menu. In the event of the failure of the Primary SonicWALL, the Secondary SonicWALL takes over to secure a reliable connection between the protected network and the Internet. Active/Active Clustering Full-Mesh Overview, Verifying Active/Active Clustering Configuration, Configuring VPN and NAT with Active/Active Clustering, Configuring Active/Active Clustering Full Mesh, Configuring Network DHCP and Interface Settings, Registering and Associating Appliances on MySonicWALL. The failover to the Secondary SonicWALL occurs when critical services are affected, physical (or logical) link detection is detected on monitored interfaces, or when the SonicWALL loses power. If neither unit in the HA pair can connect to the device, the problem is assumed to be with the device and no failover will occur. To create a free MySonicWall account click "Register". High Availability (HA) allows two identical firewalls running SonicOS to be configured to provide a reliable, continuous connection to the public Internet. Active/Active failover If all the units in the owner node for a Virtual Group encounter a fault condition, then the standby node for the Virtual Group takes over the Virtual Group ownership. Besides disabling PortShield, SuperMassive configuration is performed on only the Primary SonicWALL, with no need to perform any configuration on the Secondary SonicWALL. Enable Active/Active DPI and configure the appropriate interface as the Active/Active DPI Interface. This is different from HA monitoring. We had to wait around 10 minutes before the secondary unit had a ping reply at the WAN IP address. "Client IP" specifies that successive requests from the same client IP address will be handled by the same virtual machine. Load sharing is accomplished by configuring different Cluster Nodes as different gateways in your network. Fyi, I am using stateful HA (Gen6) with 2 PPPoE interface and its working fine & the fail-over happening in 1-2min. The Primary and Secondary SuperMassives unique LAN IP addresses cannot act as an active gateway; all systems connected to the internal LAN will need to use a virtual LAN IP address as their gateway. High Availability. Each Virtual Group has one Cluster Node acting as the owner and one or more Cluster Nodes acting as standby. When Active/Active Clustering is initially enabled, the existing IP addresses for all configured interfaces are automatically converted to virtual IP addresses for Virtual Group 1. The self-checking mechanism is managed by software diagnostics, which check the complete system integrity of the SonicWALL device. When the secondary firewall is active, the link between X0 of the secondary and port 7 of the switch is used by the firewall to manage the switch. Check "Enable Stateful Synchronization". 7. Active/Active failover transfers ownership of a Virtual Group from one Cluster Node to another. For example, you could use a smart DHCP server which distributes the gateway allocation to the PCs on the directly connected client network, or you could use policy based routes on a downstream router. This section provides conceptual information and describes how to configure High Availability (HA) in SonicOS. Note The High Availability > Monitoring page applies only to the HA pair that you are logged into, not to the entire cluster. A subset of actions are allowed on the active firewall of Non-Master nodes, and even fewer actions are allowed on firewalls in the standby state. I do have switch in between Firewall & ISP Modem. SonicWall NSA Series - High Availability. The Secondary now has all of the users session information. When more than two Cluster Nodes are configured in a cluster, these factors determine the Cluster Node that is best able to take ownership of the Virtual Group. This eliminates the possibility of configuration errors and ensures the uniqueness of the Virtual MAC address, which prevents possible conflicts. By default, this Virtual MAC address is provided by the SonicWALL firmware and is different from the physical MAC address of either the Primary or Secondary appliances. The HA port connection is used to synchronize configuration and firmware updates. A virtual MAC address is associated with each virtual IP address on an interface and is generated automatically by Sonic OS. One of the most common methods of deployment is the Active\Standby deployment, however, it can be configured in Active\Passive, Active\Active DPI and Active\Active Cluster type deployments as well. Copyright 2022 SonicWall. The enable virtual mac option is enabled and there is a switch between the ISP modem and the HA setup. In the backup SonicWall text box, enter the backup firewall's serial number as shown on the bottom (or back) of the backup unit, then click apply. shows a diagram of a 4-unit Full Mesh deployment. With Active/Active Clustering, you can assign certain traffic flows to each node in the cluster, providing load sharing in addition to redundancy, and supporting a much higher throughput without a single point of failure. Because the appliances are using the same IP address, when a failover occurs, it breaks the mapping between the IP address and MAC address in the ARP cache of all clients and network resources. If the user enters any value other than 0 or 0.0.0.0 for the router-ID, each node will be assigned a router-ID with consecutive values incremented by one for each node. These rules should be the same as the default rules created between trusted and non-trusted zoned interfaces. Login to the Primary unit in Cluster Node 1, leaving other units down. NOTE: Stateful Failover will not be available in the above setup. TZ670 NGFWs address the growing trends in web encryption, connected devices and high-speed . Hopefully this isn't getting worse with Gen7 because I'am somewhat before replacing some Gen6 Installations, including HA. Select the primary and secondary switch uplink as 23. Note Because all Cluster Nodes shares the same configuration, each node must have the same redundant ports configured and connected to the same switch(es). When enabled, OSPF runs on the OSPF-enabled interfaces of each active Cluster Node. 5. This ensures that the Secondary appliance is always ready to transition to the Active state without dropping any connections. Within each Cluster Node, Stateful HA keeps the dynamic state synchronized for seamless failover with zero loss of data on a single point of failure. We did test multiple fail-over tests but this was . Active/Active Clustering can be enabled with or without enabling Active/Active DPI, just as Active/Active DPI can be enabled with or without enabling Active/Active Clustering. The OSPF router-ID of each Cluster Node must be unique and will be derived from the router-ID configured on the Master node as follows: If the user enters 0 or 0.0.0.0 for the router-ID in the OSPF configuration, each nodes router-ID will be assigned the nodes X0 virtual IP address. A Virtual Group is a collection of virtual IP addresses for all the configured interfaces in the cluster configuration (unused/unassigned interfaces do not have virtual IP addresses). 17. Active - Describes the operative condition of a hardware unit. The HA monitoring features are consistent with previous versions. The following figure shows a sample Stateful High Availability network. The latter is the High Availability > Monitoring page. This Virtual Group functionality supports a multiple gateway model with redundancy. Afterwards, switch to the Authentication tab. Configure IP addresses for the desired interfaces on the Network > Interfaces page. Office365 Implementation and management, Security, Filter and Backups Transfer Several Domains to Office 365 exchange Microsoft SharePoint and SkyDrive Pro 2013 Deployment and Management. Select the primary and secondary management uplink as 1. 2. In the event of the failure of the Primary SonicWALL, the Backup SonicWALL takes over to . Set User Authentication Method to RADIUS. @Ajishlal ,thank you for sharing this with me. This section provides an introduction to the Active/Active Clustering feature. Start up the other units in the Active/Active cluster. High Availability provides a way to share Dell SonicWALL licenses between two Dell SonicWALL security appliances when one is acting as a high-availability system for the other. Under the Settings tab, type the username and password and from the drop down list under One-Time password method, select> TOTP . For example, every SonicWALL firewall uses redundant ports to connect twice to each networking device. Todays routers do attempt to forward packets with a consistent next-hop for each packet flow, but this applies only to packets forwarded in one direction. Of these, two have configurable settings that pertain to Active/Active Clustering, one displays status for both the cluster and the HA pair to which you are logged in, and one pertains only to configuration for the local HA pair. 4. Firmware or signature updates, changes to policies, and other configuration changes cannot be synchronized to other Cluster Nodes until the HA port connection is fixed. The following sections describe how to prepare, configure, and verify HA and Active/Active Clustering: Active/Standby and Active/Active DPI HA Prerequisites, Configuring Active/Active Clustering and HA, Verifying Active/Active Clustering Configuration, Configuring VPN and NAT with Active/Active Clustering, Configuring Active/Active Clustering Full Mesh. Login to the Primary unit, leaving other units down. NOTE:The Firewall Uplink and Switch Uplink options are set the same in this configuration to support the redundant firewalls. This section contains the following subsections: How Does Stateful Synchronization Work? When physical interface monitoring is enabled, with or without logical monitoring enabled, HA failover takes precedence over Active/Active failover. The following features are not supported when Active/Active Clustering is enabled: The following features are only supported on Virtual Group 1: The Active/Active Clustering feature is not backward compatible. Active/Active DPI can be enabled, providing increased throughput within each Cluster Node. Port redundancy, in which an unused port is assigned as a secondary to another port, provides protection at the interface level without requiring failover to another firewall or node. MGMT interfaces and HA: The ACTIVE unit will always listen on what is configured for the MGMT interface on the Manage | Network | Interfaces page | "IP Address . From a routing perspective, all Cluster Nodes will appear as parallel routers with the virtual IP address of the Cluster Nodes interface. Select the firewall uplink as Interface X0. TIP: Session persistence specifies that traffic from a client should be handled by the same virtual machine in the backend pool for the duration of a session. Click Configure icon for an interface on the LAN, such as X0. The following table lists the information that is synchronized and information that is not currently synchronized by Stateful Synchronization. Featuring a high port density (including 16 x 1GbE ports and three x 10 GbE ports), the solution supports network and hardware redundancy with high . Configure settings in the High Availability > Advanced page. The HA feature has a thorough self-diagnostic mechanism for both the Primary and Secondary SuperMassives. There is a weighting mechanism on both sides to decide which side has better connectivity, used to avoid potential failover looping. During normal operation, the Primary SonicWALL is in an Active state and the Secondary SonicWALL in an Standby state. Configure the Load balancing rules to access the internal Virtual Machines from the public network. Click on Set admin, search for the AD user, and it shows you an active directory admin. The Virtual MAC address greatly simplifies this process by using the same MAC address for both the Primary and Secondary appliances. A WAN interface failure can trigger either a WLB failover, an HA pair failover, or an Active/Active failover to another Cluster Node, depending on the following: WAN goes down logically due to WLB probe failure WLB failover, Physical WAN goes down while Physical Monitoring is enabled HA pair failover, Physical WAN goes down while Physical Monitoring is not enabled Active/Active failover, Routing Topology and Protocol Compatibility. While it is possible to connect a redundant switch without using a redundant port, this involves complex configuration using probes. For example, in a 4-node cluster, if the router-ID 10.0.0.1 was configured on the Master node, the router-IDs assigned would be as follows: RIP is supported, and like OSPF, will run on the RIP-enabled interfaces of each Cluster Node. We will go through the UI to cover how its done, and we will also perform an OS upgrade while a VoIP call is going through. Note that non-management traffic is ignored if it is sent to one of the monitoring IP addresses. When using logical monitoring, the HA pair will ping the specified Logical Probe IP address target from the Primary as well as from the Secondary SonicWALL. Click MANAGE in the top navigation menu. This allows synchronization of licenses (such as the Active/Active Clustering or the Stateful HA license) between the standby unit and the SonicWALL licensing server. Configuring monitoring IP addresses for both units in the HA pair allows you to log in to each unit independently for management purposes. If both units can successfully ping the target, no failover occurs. The Secondary identifier is a relational designation, and is assumed by a unit when paired with a Primary unit. . Configure IP addresses for the desired interfaces on the Network > Interfaces page. The Primary identifier is a manual designation, and is not subject to conditional changes. Layer-2 Bridged interfaces are not supported in a cluster configuration. Note Before performing the procedures described in this section, ensure that you have completed the prerequisites described in Active/Standby and Active/Active DPI HA Prerequisites. It features both inbuilt and an expandable storage of up to 256GB, that enables various features including logging, reporting, caching, firmware backup and more. These NAT policies extend existing NAT policies for particular interfaces to the corresponding virtual interfaces. 6. Resolution. This is in contrast to traditional IP routing in which each packet in a flow may technically be forwarded along a different path as long as it arrives at its intended destination the intervening routers do not have to see every packet. Upon failure of the Primary unit, the Secondary unit will assume the Active role. It provides full deep packet inspection (DPI) without diminishing network performance, thus eliminating bottlenecks that other products introduce, while enabling businesses to realize increased productivity gains. Create a full mesh configuration of NAT rules in the cluster so every interface-pair has a NAT rule which replaces the source IP address in the packet with the virtual IP of the egress interface. In the case of failure of the HA port connection, SVRRP heartbeat messages are sent on the X0 interface. The section About Failover provides more information about how failover works. Add to Cart. Certain packet flows on the active unit are selected and offloaded to the standby unit on the Active/Active DPI Interface. How Does Active/Active Clustering Work? The failover to the Secondary SonicWALL occurs when critical services are affected, physical (or logical) link failure is detected on monitored interfaces, or when the Primary SonicWALL loses power. The same interface can have multiple virtual IP addresses, one for each Virtual Group that is configured. The owner of Virtual Group 1 is designated as the Master Node, and is responsible for synchronizing configuration and firmware to the other nodes in the cluster. 2. This document describes the configuration options for all High Availability settings, whether they pertain to Active/Active Clustering or only to the HA pair. The traditional SonicWALL High Availability protocol or Stateful HA protocol is used for communication within the Cluster Node, between the units in the HA pair. Active/Active Clustering Full Mesh configuration is an enhancement to the Active/Active Clustering configuration option and provides the highest level of availability possible with high performance. 22. The High availability is configured in stateless mode since stateful does not work with PPPoE. The interface must be the same number on both appliances. Active/Active Clustering also introduces the concept of Virtual Groups. The Secondary appliance begins to send gratuitous ARP messages to the LAN and WAN switches using the same Virtual MAC address and IP address as the Primary appliance. All configuration changes are performed on the Primary appliance and automatically propagated to the Secondary appliance. Asymmetric Routing Issues In Cluster Configurations. Feature Support Information with Active/Active Clustering. While all Cluster Nodes are up and processing traffic normally, redundant ports remain standby and are ready for use if the partner port goes down for any reason. When Active/Active Clustering is enabled, the SonicOS internal DHCP server is turned off and cannot be enabled. Minimal impact on bandwidth - Transmission of synchronization data is throttled so as not interfere with other data. After Active/Active Clustering is enabled, you must select the Virtual Group number during configuration when adding a VPN policy. Under normal operating conditions, the Secondary unit operates in an Standby mode. The traditional SonicWALL High Availability protocol or Stateful HA protocol is used for communication within the Cluster Node, between the units in the HA pair. HA overview video: https://youtu.be/q-XtKroK2QcSonicWall HA KB with prerequisites: https://www.sonicwall.com/support/knowledge-base/how-to-configure-high-availability-ha/170503978252820/tips and tricks video: https://youtu.be/UidYViKgr8w ), it immediately informs the Secondary appliance. Navigate to High Availability | Settings. This provides load sharing. OSPF is supported with Active/Active Clustering. Start up the other units in the Active/Active cluster. The High availability is configured in stateless mode since stateful does not work with PPPoE. In general, any network advertised by one node will be advertised by all other nodes. And the HA deployment I usually see in enterprise: Two firewall, two switches stacked using LACP providing no single point of failure. There are two ways to avoid asymmetric routing paths: 1. Select the primary and secondary switch uplink as 1. When using SonicWALL Global Management System (GMS) to manage the appliances, GMS logs into the shared WAN IP address. Thus, Virtual Group 1 will include virtual IP addresses for X0, X1, and any other interfaces which are configured and assigned to a zone. See Licensing High Availability Features. One mention: when you power on the HA appliance for the first time, it is factory default and just like every SonicWall appliance, it is DHCP on X0. Configure the Mode as " Active / Standby ". Ports 10 on both Switch 1 and Switch 2 are portshielded to X0, and hosts connected to Ports 10 on both switches can communicate using the common uplink. Cisco, HP and Sonicwall networking equipment. HA monitoring can be configured for both physical/link monitoring and logical/probe monitoring. 10. Virtual Group 1 traffic is sent on X3, while Virtual Group 2 traffic is sent on X4. When the primary unit is in Active HA mode, traffic between H1 and X3 is carried over the dedicated link between X3 and 12, and traffic between H3 and X4 is carried over the dedicated link between X4 and 13.When the secondary unit is in Active HA mode, traffic between H1 and X3 is carried over the dedicated link between X3 and 14, and traffic between H3 and X4 is carried over the dedicated link between X4 and 15.The link between the firewall interface, X0, and port 1 on the switch, carries the management traffic to manage the switch from the firewall. Navigate to high availability and enable it by ticking on the high availability check box and clicking on the apply button. To enable link detection between the designated HA interfaces on the Primary and Backup units, leave the Enable Physical . The following sections provide overviews of SonicWALLs implementation of HA: Active/Active Clustering Full-Mesh Overview. This greatly simplifies the failover process as only the connected switches need to update their learning tables. Select the firewall uplink as Interface X2. Configuring HA Using Two Switch Management PortsYou can connect X0 of the primary and secondary firewalls directly to the ports on the switch. Yes. The above deployment is an Active/Active HA. SonicWall NSa 2650 High Availability. On Cluster Node ID 2 set the Virtual Group 1 Rank as Standby and Virtual Group 2 Rank as Owner. Optionally, you can manually configure the Virtual MAC address on the High Availability > Monitoring page. When the full mesh NAT rules are in place, the forward and reverse paths of flows transiting the cluster will always flow through the same Cluster Node (or the current owner of the Cluster Nodes primary virtual IP addresses). Select the firewall uplink as Interface X3. If Cluster Node 2 goes down, Virtual Group 2 is now also owned by Cluster Node 1. The High Availability pair uses the same LAN and WAN IP addressesregardless of which appliance is currently Active. SonicWall offers multiple method of configuring High Availability. This KB explains how SonicWall switches can be deployed with the SonicWall UTM devices in high availability mode.The switches can be deployed with one or two dedicated uplinks and also with common uplinks. High Availability (HA) allows two identical firewalls running SonicOS to be configured to provide a reliable, continuous connection to the public Internet. Optionally, for port redundancy for Active/Active DPI ports, physically connect a second interface between the two appliances in each HA pair. SVRRP is used to communicate Virtual Group link status and ownership status to all Cluster Nodes in the cluster. In this case, twoswitch ports are used on the switch for management traffic.HA Pair Using 2 Switch Management Ports Topology shows a firewall HA pair with a switch and two dedicatedlinks: X0 of the primary unit is connected to port 1. X0 of the secondary unit is connected to port 7. Physical interface monitoring enables link detection for the monitored interfaces. Redundancy is achieved at several levels with Active/Active Clustering: The cluster provides redundant Cluster Nodes, each of which can handle the traffic flows of any other Cluster Node, if a failure occurs. HA allows two identical SuperMassives running SonicOS to be configured to provide a reliable, continuous connection to the public Internet.One SonicWALL device is configured as the Primary unit, and an identical SonicWALL device is configured as the Secondary unit. In the event of the failure of an entire Cluster Node, the failover will be stateless. In this video I will deploy and test HA using the two most common deploy. Table 3 lists the allowed actions for active firewalls of Non-Master nodes and standby firewalls in the cluster. As with OSPF and RIP, configuration changes made on the Master node will be applied to all other Cluster Nodes. I am going to use Sonicwall NSa 4650 Firewall. Currently, a maximum of four Virtual Groups are supported. 5. Installed high availability Big IP F5 LTM and GTM load balancers to provide uninterrupted service to customers. You do not need to purchase a second set of licenses for the Secondary unit in a High Availability Pair. A Virtual Group can also be thought of as a logical group of traffic flows within a failover context, in that the logical group of traffic flows can failover from one node to another depending upon the fault conditions encountered. Virtual Group Link Weight of the Cluster Nodes This is the number of interfaces in the Virtual Group that are up and have a configured virtual IP address. For example, a redundant switch might be deployed on the WAN side if traffic passing through it is business-critical. 4. Configure per-unit IP addresses in the High Availability > Monitoring page. You can unsubscribe at any time from the Preference Center. The Secondary unit does not receive heartbeat messages from the Primary appliance and switches from Standby to Active mode. The Primary and Secondary IP addresses configured on the High Availability > Monitoring page can be configured on LAN or WAN interfaces, and are used for multiple purposes: As independent management addresses for each unit, regardless of the Active or Standby status of the unit (supported on all physical interfaces), To allow synchronization of licenses between the standby unit and the SonicWALL licensing server, As the source IP addresses for the probe pings sent out during logical monitoring. All devices in the Cluster must be of same product model and be running the same firmware version. HA provides a way to share SonicWALL licenses between two SuperMassives when one is acting as a high availability system for the other. A security ecosystem to harness the power of the cloud, Protect Federal Agencies and Networks with scalable, purpose-built cybersecurity solutions, Access to deal registration, MDF, sales and marketing tools, training and more, Find answers to your questions by searching across our knowledge base, community, technical documentation and video tutorials, 08/19/2020 3 People found this article helpful 170,872 Views, Azure lets you add cloud capabilities to your existing network through its platform as a service (PaaS) model or entrust Microsoft with all your computing and network needs with Infrastructure as a Service (IaaS).Product Matrix Topology. ), and uses redundant upstream routers in addition to redundant switches. -Deploy, upgrade, review, and document network infrastructure, including high availability firewalls and stacked switching; Install and configure Windows Servers, peripherals, network devices and storage devices in accordance with internal standards and project requirements. The virtual MAC address is created in the format 00-17-c5-6a-XX-YY, where XX is the interface number such as 03 for port X3, and YY is the internal group number such as 00 for Virtual Group 1, or 01 for Virtual Group 2. Preempt mode means that, after failover between two Cluster Nodes, the original owner node for the Virtual Group will seize the active role from the standby node after the owner node has been restored to a verified operational state. Configuring HA and PortShields With Dedicated Uplink(s). Active/Active failover always operates in Active/Active preempt mode. For communication between Cluster Nodes, a new protocol called SonicWALL Virtual Router Redundancy Protocol (SVRRP) is used. The latest SonicWall TZ270 series, are the first desktop form factor nextgeneration firewalls (NGFW) with 10 or 5 Gigabit Ethernet interfaces. Add to Cart. The documentation of SonicWALL (G6 and G7 says that stateful should be disabled), but of course this is very useful information. In this configuration with PortShield functionality in HA mode, firewall interfaces that serve as PortShield hosts should be connected to the switch on active and standby units. For communication between Cluster Nodes in an Active/Active cluster, a new protocol called SonicWALL Virtual Router Redundancy Protocol (SVRRP) is used. When Active/Active Clustering is enabled for the first time, the configured IP addresses for the interfaces on that firewall are converted to virtual IP addresses for Virtual Group 1. 6. A packet arriving on a Virtual Group will leave the firewall on the same Virtual Group. Resolution. You need to configure these virtual IP addresses on the Network > Interfaces page. Navigate to network -> interfaces and look for the high availability HA . A typical recommended setup includes four firewalls of the same SonicWALL model configured as two Cluster Nodes, where each node consists of one Stateful HA pair. A Cluster Node can consist of a Stateful HA pair, a Stateless HA pair or a single standalone unit. 11. Select Active/Active DPI on the High Availability > Settings page. Note When HA Monitoring/Management IP addresses are configured only on WAN interfaces, they need to be configured on all the WAN interfaces for which a Virtual IP address has been configured. After logging into the Master Node, monitoring configuration needs to be added on a per Node basis from the High Availability > Monitoring page. 2. All rights Reserved. LabTech was the RMM software. 3. The link is sensed at the physical layer to determine link viability. Note When Active/Active Clustering is enabled, the SonicOS internal DHCP server is turned off. Critical internal system processes such as NAT, VPN, and DHCP (among others) are checked in real time. Routers make no attempt to direct return traffic to the originating router. A customer of us have a TZ670 in High Availability setup with a PPPoE fiber internet connection. Go to Manage In top menu , navigate to High Availability | Monitoring Settings . Click CONFIGURE RADIUS on the right. Both appliances must be the same Dell SonicWALL model. NOTE: The local hosted Virtual Subnets will not be accessed through the Public IP once the route table is created on Azure. This will cause traffic to be dropped by one or both Cluster Nodes since neither is seeing all of the traffic from the flow. Start up the other units in the Active/Active cluster. The enable virtual mac option is enabled and there is a switch between the ISP modem and the HA setup. The preferences can then be imported without potential conflicts after upgrading. A Virtual Group is only owned by one Cluster Node at a time, and that node becomes the owner of all the virtual IP addresses associated with that Virtual Group. . This section describes the requirements for registering your Dell SonicWALL network security appliance and licensing the SonicWALL High Availability features. CAUTION:Load Balancer uses a distributed probing service for its internal health model. To configure High Availability on the Primary SonicWall, perform the following steps: Login to the SonicWall management Interface. Convergence time is the amount of time it takes for the devices in a network to adapt their routing tables to the changes introduced by high availability. Full Mesh deployments provide a very high level of availability for the network, because all devices have one or more redundant partners, including routers, switches, and security appliances. - Provide and apply the recommended Firewalls design changes for enhancing performance, availability and provide more restriction on the . 12. In this video I will deploy and test HA using the two most common deployments I have seen. Networks needing a DHCP server can use an external DHCP server which is aware of the multiple gateways, so that the gateway allocation can be distributed. 10. The one I see in many SMB: Two firewalls and one switch. Enter the serial numbers of other units in the Active/Active cluster. Two appliances configured in this way are also known as a High Availability Pair (HA Pair). If the timestamps are out of sync and the Standby unit is available, a complete synchronization is pushed to the Standby unit. A customer of us have a TZ670 in High Availability setup with a PPPoE fiber internet connection. Cost-effectiveness High Availability is a cost-effective option for deployments that provide high availability by using redundant SuperMassives. Full Mesh is not required when deploying redundant ports or switches, but a Full Mesh deployment includes them. Configuring HA Using Two Switch Management Ports, ICMP Ping Latency with SonicWall switches, How to enable/configure SNMP on sonicwall switches. Logical monitoring involves configuring the SonicWALL to monitor a reliable device on one or more of the connected networks. Fill in all necessary information like Serial number, IP address, username, password. Primary - Describes the principal hardware unit itself. Configure settings in the High Availability > Advanced page. The Cluster Node that becomes the Virtual Group owner also becomes the owner of all the virtual IP addresses associated with the Virtual Group and starts using the corresponding virtual MAC addresses. You can view these NAT policies in the Network > NAT Policies page. . NOTE: The above configuration will deploy NSv_Azure_HA1, NSv_Azure_HA2 along with external Load balancer NSv_Azure_HA-ELB and internal Load balancer NSv_Azure_HA-ILB. The owner of Virtual Group 1 is designated as the Master Node. On a particular interface, virtual IP addresses for Virtual Group 1 must be configured before other Virtual Groups can be configured. If the owner node for a Virtual Group encounters a fault condition, one of the standby nodes will become the owner. 5. The power is unplugged from the Primary appliance and it goes down. The SonicWall TZ670 is a desktop-form-factor next-generation firewall (NGFW) with 10 Gigabit Ethernet interfaces. The Virtual MAC setting is available even if Stateful High Availability is not licensed. If Stateful HA is enabled for the pair, the failover occurs without interruption to network connections. On the Network > DHCP Server page, disable the DHCP server and delete all DHCP server lease scopes. Preempt - Applies to a post-failover condition in which the Primary unit has failed, and the Secondary unit has assumed the Active role. 2. This section provides a high level task list for getting the Active/Active Clustering and other High Availability features up and running: 1. A redundant switch can be deployed anywhere in the network depending on the need for high availability. Typically this is handled by another device downstream (closer to the LAN devices) from the Active/Active Cluster, such as a DHCP server or a router. Figure 50:15 4-Unit Full Mesh Deployment, You can also configure a Full Mesh deployment using only two firewalls, one per Cluster Node. The PortShield members should also be connected to ports on the switch. Similarly, the link between X2 and Switch 2 is set up as a common uplink. 17. An Active/Active Cluster is formed by a collection of Cluster Nodes. If the Primary device loses connectivity, the Secondary SonicWALL transitions to Active mode and assumes the configuration and role of Primary, including the interface IP addresses of the configured interfaces. 8. NOTE:To use the switch with HA, you must first deploy the firewalls in high availability, and then add the switch. 18. Add to Cart. Next-generation firewall for SMB, Enterprise, and Government, Comprehensive security for your network security solution, Modern Security Management for todays security landscape, Advanced Threat Protection for modern threat landscape, High-speed network switching for business connectivity, Protect against todays advanced email threats, Next-generation firewall capabilities in the cloud, Stop advanced threats and rollback the damage caused by malware, Control access to unwanted and unsecure web content. Check " Enable Stateful Synchronization ". 6. To use the switch with HA, you must first deploy the firewalls in high availability, and then add the switch. With Active/Active DPI enabled on a Stateful HA pair, these DPI services are processed on the standby firewall of an HA pair concurrently with the processing of firewall, NAT, and other modules on the active firewall. All other network devices continue to use the same virtual MAC addresses and do not need to update their ARP tables, because the mapping between the virtual IP addresses and virtual MAC addresses is not broken. Check "Enable Virtual MAC". 21. We did test multiple fail-over tests but this was very bad before there was any connection available at the secondary. This section provides an introduction to the Stateful Synchronization feature. The traditional SonicWALL High Availability protocol or Stateful HA protocol is used for communication within the Cluster Node, between the units in the HA pair. But, if one SonicWALL can ping the target but the other SonicWALL cannot, the HA pair will failover to the SonicWALL that can ping the target. Additional NAT policies can be configured as needed and can be made specific to a Virtual Group if desired. Worked on configuring and troubleshooting Nodes, Pools, Profiles, Virtual Servers, SSL Certificates, iRules, and SNATs on the F5 Big IPs using the Web GUI and CLI; Involved in Network Designing, Routing, DNS, IP subnetting, TCP/IP . Active/Active Clustering configuration can include configuring Virtual Group IDs and redundant ports. Stateful Synchronization provides dramatically improved failover performance. In a larger deployment, if Cluster Node 1 owns three or four Virtual Groups, traffic is distributed among the redundant ports traffic for Virtual Groups 1 & 3 is sent on X3, while traffic for Virtual Groups 2 & 4 is sent on X4. The management IP address of the Secondary unit is used to allow license synchronization with the SonicWALL licensing server, which handles licensing on a per-appliance basis (not per-HA pair). Configure settings in the High Availability > Advanced page. A PC user connects to the network, and the Primary SuperMassive creates a session for the user. The original owner will have a higher priority for a Virtual Group due to its higher ranking if all virtual IP interfaces are up and the link weight is the same between the two Cluster Nodes. Secondary - Describes the subordinate hardware unit itself. . SVRRP is also used to synchronize configuration changes, firmware updates, and signature updates from the Master Node to all nodes in the cluster. The Secondary appliance must issue an ARP request, announcing the new MAC address/IP address pair. The result is asymmetric routing, in which the flow of packets in one direction go through a node different than that used for the return path. The Virtual MAC address allows the High Availability pair to share the same MAC address, which dramatically reduces convergence time following a failover. Power down all the units except the unit that is to be designated as the Primary unit in Cluster Node 1. Easy to set-up and manage: Stateful firewall and router cloud managed with the Meraki Go mobile app; easily add multiple admins to help manage your networking equipment . When upgrading to SonicOS from a previous release that did not support Active/Active Clustering, it is highly recommended that you disable High Availability before exporting the preferences from an HA pair running a previous version of SonicOS. In a cluster with two Cluster Nodes, one of which has a fault, naturally the other will take ownership. Note All Cluster Nodes in the Active/Active cluster share the same configuration. Stateful HA is not required, but is highly recommended for best performance during failover. Do you also have a switch between ISP modem and SonicWALL's? By submitting this form, you agree to our Terms of Use and acknowledge our Privacy Statement. The link between the firewall interface serving as the PortShield host and the switch is set up as a dedicated uplink.HA Pair Using One Switch Management Port Topology shows a firewall HA pair with a switch and one dedicated link: The firewall interfaces, X3 and X4, on the primary unit are connected to ports 12 and 13 on the switch. X3 and X4 are configured as PortShield hosts. Similarly, the firewall interfaces X3 and X4 on the secondary unit are connected to ports 14 and 15 on the switch. Ports 12 and 14 on the switch are port shielded to X3 with the dedicated uplink option enabled. Ports 13 and 15 on the switch are port shielded to X4 with the dedicated uplink option enabled. Ports 2 and 4 are port shielded to X3. Ports 3 and 5 are port shielded to X4. 3. You can view these virtual IP addresses in the Network > Interfaces page. Even if the standby unit was already registered on MySonicWALL before creating the HA association, you must use the link on the System > Licenses page to connect to the SonicWALL server while accessing the Secondary appliance through its management IP address. The Gen 7 TZ series are highly scalable, with high port density of up to 10 ports. Select the primary and secondary switch uplink as 1. As the Primary appliance creates and updates network connection information (VPN tunnels, active users, connection cache entries, etc. If each Cluster Node is an HA pair, the cluster will include eight firewalls. For example, connect X4 on the Primary unit to X4 on the Secondary. HA requires one SonicWALL device configured as the Primary SonicWALL, and an identical SonicWALL device configured as the Secondary SonicWALL. The SonicWall Network Security Appliance (NSA) series combines the patented SonicWall Reassembly Free Deep Packet Inspection (RFDPI) engine with a powerful and massively scalable multi-core architecture to deliver intrusion prevention, gateway anti-virus, gateway anti-spyware, and application intelligence and control for businesses of all sizes. 7. Preform the tasks described in Active/Standby and Active/Active DPI HA Prerequisites, including registering and associating the appliances on MySonicWALL and licensing the high availability features. When Virtual MAC is enabled, it is always used even if Stateful Synchronization is not enabled. Any network appliance that performs deep packet inspection or stateful firewall activity must see all packets associated with a packet flow. For more information about Full Mesh deployments, see the Active/Active Clustering Full Mesh Deployment Technote. For larger deployments, the cluster can include eight firewalls, configured as four Cluster Nodes (or HA pairs). Configure settings in the High Availability > Advanced page. The diagnostics check internal system status, system process status, and network connectivity. License Synchronization with SonicWALL License Manager, HA Synchronize Settings (syncs settings to the HA peer within the node), HA Synchronize Firmware (syncs firmware to the HA peer within the node), Authentication tests (such as test LDAP, test RADIUS, test Authentication Agent). Note Per-unit IP addresses (HA monitoring IP addresses) are required for all the units in the cluster either on Primary LAN or on Primary WAN Interfaces. Qualification of failure is achieved by various configurable physical and logical monitoring facilities described throughout the Task List section. Without Virtual MAC enabled, the Active and Standby appliances each have their own MAC addresses. Configure Virtual Group IP addresses on the Network > Interfaces page. Dynamic state synchronization is only available in a Cluster Node if it is a Stateful HA pair. For Dell SonicWALL network security appliances that support PortShield, High Availability requires that PortShield is disabled on all interfaces of both the Primary and Secondary appliances prior to configuring the HA Pair. From a routing perspective, all Cluster Nodes appear as parallel routers, each with the virtual IP address of the Cluster Node's interface. HA Conversion License to Standalone Unit for TZ570 Series The NSa 4700 has been built from the ground up with the latest hardware components, all designed to deliver multi-gigabit threat prevention throughput " even for encrypted traffic. Login to the SONICWALL Appliance, Navigate to DEVICE | Users | Local Users. Both appliances must be the same SonicWALL model. Note Default NAT policies will be created automatically, so there is no need to configure NAT policies for Virtual Groups in the Network > NAT Policies page. The SonicWall is the high performing, secure Unified Threat Management (UTM) firewall. This chapter provides conceptual information and describes how to configure High Availability (HA) in SonicOS. To set up HA with two switch management ports, Configuring HA and PortShield With a Common Uplink. The standby unit only sees the network traffic offloaded by the active unit, and processing of all modules other than DPI services is restricted to the active unit. There are two factors in determining Virtual Group ownership (which Cluster Node will own which Virtual Group): Rank of the Cluster Node The rank is configured in the SonicOS management interface to specify the priority of each node for taking over the ownership of a Virtual Group. All clients and remote sites continue to use the same Virtual MAC address and IP address without interruption. Failure to periodically communicate with the device by the active unit in the HA pair will trigger a failover to the standby unit. . A Full Mesh deployment uses redundant ports on each of the main traffic ports (LAN, WAN, etc. Faster failover performance - By maintaining continuous synchronization between the Primary and Secondary appliances, Stateful Synchronization enables the Secondary appliance to take over in case of a failure with virtually no down time or loss of network connections. When Stateful Synchronization is enabled, the Primary appliance actively communicates with the Secondary to update most network connection information. In case of a fault condition on one of the firewalls in this deployment, the failover is not stateful since neither firewall in the Cluster Node has an HA Secondary. Add to Cart for Pricing. The remaining processing is performed on the active unit. In this configuration with PortShield functionality in HA mode, a link between the active/standby firewalls and the switch serves as a common uplink to carry all the port shielded traffic. This IP routing behavior presents problems for a firewall cluster because the set of Cluster Nodes all provide a path to the same networks. This chapter contains the following main . Note Stateful High Availability is not supported on SonicWALL TZ series appliances. Standby - Describes the passive condition of a hardware unit. This section describes the current limitations and special requirements for Active/Active Clustering configurations with regard to routing topology and routing protocols. Please can anyone provide step-by-step tutorial for configuring a high availability cluster (active-standby) with two Sonicwall 4650 firewalls. Physically connect the LAN and WAN ports of all units to the appropriate switches. Click Device in the top navigation menu. A security ecosystem to harness the power of the cloud, Protect Federal Agencies and Networks with scalable, purpose-built cybersecurity solutions, Access to deal registration, MDF, sales and marketing tools, training and more, Find answers to your questions by searching across our knowledge base, community, technical documentation and video tutorials, 03/25/2021 33 People found this article helpful 173,823 Views. Configure per-unit IP addresses in the High Availability > Monitoring page. 8. Firewall interfaces that serve as PortShield hosts are connected to a separate switch (not necessarily a switch) and not the same switch connected to the active and standby units. The PortShield hosts X0 are connected to a different switch (which could be a SonicWall switch or any other vendors switch) to avoid looping of packets. The Cluster Nodes are configured with redundant ports, X3 and X4. Physical monitoring cannot be disabled for these interfaces. When Active/Active Clustering is enabled, HA monitoring configuration is supported for the HA pair in each Cluster Node. DPI is performed on the standby unit and then the results are returned to the active unit over the same interface. Stateful HA will provides Improved reliability & Faster Failover performance. MUST BE PAIRED WITH A REGULAR SonicWall NSa 3650 FIREWALL. Click on Add. Until this ARP request propagates through the network, traffic intended for the Primary appliances MAC address can be lost. Hi @Jour I can only speak for Gen6 in HA with PPPoE and there it usually takes 1-2 Minutes when the failover happens. Cluster Node management and monitoring state messages are sent using SVRRP over the HA port connection. Routers forwarding packets to networks through the cluster may choose any of the Cluster Nodes as the next-hop. The Secondary SonicWALL maintains a real-time mirrored configuration of the Primary SonicWALL via an Ethernet link between the designated HA ports of the appliances. See the following sections for descriptions of these new concepts and changes to existing functionality: About Redundant Ports and Redundant Switches. There are several important concepts that are introduced for Active/Active Clustering. SonicWall TZ570 High Availability SonicWall TZ570 High Availability Appliance #02-SSC-5694. Note The Active/Active virtual MAC address is different from the High Availability virtual MAC address. When the PC user attempts to access a Web page, the Secondary appliance has all of the users session information and is able to continue the users session without interruption. The synchronization traffic is throttled to ensure that it does not interfere with regular network traffic. SonicWall NSa 3650 High Availability. When Active/Active Clustering is enabled, only static IP addresses can be used on the WAN. Clicking the button opens the RADIUS Configuration window. High_Availability. Sonicwall VPN solution provides our employees with secure access to internal and external data and resources. 1. Microsoft does not support L2 HA deployment and requires manually Sync by importing the .exp file every time from NSv_Azure_HA-01 to NSv_Azure_HA-02 or with the help of Cloud GMS. When configuring a redundant port, the interface must be unused; that is, not assigned to any zone. 17. . I am a little bit confused that stateful works in your situation. This field is for validation purposes and should be left unchanged. No routing updates are necessary for downstream or upstream network devices. Convergence time is the amount of time it takes for the devices in a network to adapt their routing tables to the changes introduced by high availability. High Availability allows two identical SonicWALL security appliances running SonicOS Enhanced to be configured to provide a reliable, continuous connection to the public Internet.One SonicWALL device is configured as the Primary unit, and an identical SonicWALL device is configured as the Backup unit. It is an active-standby configuration where the Primary appliance handles all traffic. All actions are allowed for admin users with appropriate privileges on the active firewall of the Master Node, including all configuration actions. Status should look as below under Monitor | High Availability Status. ARM template deployment, click Deploy to Azure. 5. The Active identifier is a logical role that can be assumed by either a Primary or Secondary hardware unit. The Primary appliance synchronizes with the Secondary appliance. If both physical monitoring and logical monitoring are disabled, Active/Active failover will occur on link failure or port disconnect. Enter the Cluster Node owner/standby rankings for each Virtual Group. Expand Users and select Settings. The IP address set in the Primary IP Address or Secondary IP Address field is used as the source IP address for the ping. If the timestamps are in sync and a change is made on the Active unit, an incremental synchronization is pushed to the Standby unit. This means that pre-existing network connections must be rebuilt. On the High Availability > Settings page, select Active/Standby. To use the Active/Active DPI feature, the administrator must configure an additional interface as the Active/Active DPI Interface. The Standby unit assumes the Active role in the event of determinable failure of the Active unit. When incremental synchronization fails, a complete synchronization is automatically attempted. On the Network > DHCP Server page, disable the DHCP server and delete all DHCP server lease scopes. As part of the configuration for Active/Active Clustering, the serial numbers of other firewalls in the cluster are entered into the SonicOS management interface, and a ranking number for the standby order is assigned to each. The failover applies to loss of functionality or network-layer connectivity on the Primary SonicWALL. Configure Virtual Group IP addresses on the Network > Interfaces page. Dynamic WAN clients (L2TP, PPPoE, and PPTP), Deep Packet Inspection (GAV, IPS, and Anti Spyware), IPHelper bindings (such as NetBIOS and DHCP), Dynamic ARP entries and ARP cache timeouts. In a typical configuration, each Cluster Node owns a Virtual Group, and therefore processes traffic corresponding to one Virtual Group.

Configuring Active/Active Clustering and HA. Also, X0 on the primary as well as the secondary is ensured to be connected to port 1 of the switch (for example, via a hub) so that when the secondary firewall becomes the active unit, the switch can be managed via the linkbetween the firewall interface X0 on the secondary and port 1 of the switch. To find the Inbound NSv GUI Access rule on port number 8443 and 8444, Configure the Load balancing rules to forward the internal Virtual Machines traffic through ILB, Adding an access rule to allow interesting traffic, Adding a NAT ruleto allow interesting traffic and translating the source as X0 ip, Adding a route rule replying to the Internal Load balancer probe on 443 port. Physically connect an additional interface between the two appliances in each HA pair if you plan to enable Active/Active DPI. Stateful HA Upgrade for TZ570 Series Enables Stateful High Availability feature #02-SSC-5891 List Price: $786.00 Our Price: $686.81. If you choose to make X5 the Active/Active DPI Interface, you must physically connect X5 on the active unit to X5 on the standby unit in the HA pair. To use this feature, you must register the Dell SonicWALL appliances on MySonicWALL as Associated Products. Use the Virtual Mac option: Go to Manage | High Availability | Base Setup | General | Select Enable Virtual MAC . Minimal impact on CPU performance - Typically less than 1% usage. After enabling Stateful Synchronization on the appliances in the HA pair and connecting and configuring the Active/Active DPI Interface(s), you can enable Active/Active DPI on the High Availability > Settings page. The Cluster Node consists of a Stateful HA pair, in which the Secondary firewall can assume the duties of the Primary unit in case of failure. Login to each unit using the per-unit IP address, and click Register and synchronize licenses with the MySonicWALL Licensing server. Select Active/Active Clustering Link/Interface under HA | Settings | HA Interfaces. The Master Node is also responsible for synchronizing firmware to the other nodes in the cluster. The following sections provides feature support information about Active/Active Clustering: Routing Topology and Protocol Compatibility. Select the firewall uplink as Interface X0. Create a User. Click on Save to update the active directory admin for your Azure SQL Server. Enter the serial numbers of other units in the Active/Standby HA pair. BGP is supported in clusters, and will also appear as parallel BGP routers using the virtual IP address of the Cluster Nodes interface. You can unsubscribe at any time from the Preference Center. Layer 2 broadcasts inform the network devices of the change in topology as the Cluster Node which is the new owner of a Virtual Group generates ARP requests with the virtual MACs for the newly owned virtual IP addresses. You can use the following name servers to point websites too; au- dns .f2hcloud.com | 139.99.135.201 - Australia. NOTE: The above configuration will deploy NSv_Azure_HA1, NSv_Azure_HA2 along with external Load balancer NSv_Azure_HA-ELB and internal Load balancer NSv_Azure_HA-ILB. How to Configure Stateful Active-Standby High Availability in Gen6 UTM Appliances But it's good to hear that it works for others in Gen 6 with a fail over time of 1-2 min. To set up HA with a common uplink:For switch 1: This field is for validation purposes and should be left unchanged. Failover - Describes the actual process in which the Standby unit assumes the Active role following a qualified failure of the Active unit. Active/Standby and Active/Active DPI HA Prerequisites. Click on Add Users. If the firmware configuration becomes corrupted on the Primary SonicWALL, the Secondary SonicWALL automatically refreshes the Primary SonicWALL with the last-known-good copy of the configuration preferences. Load Balancer health probes originate from the IP address 168.63.129.16 and must not be blocked for probes to mark up your instance. Must be paired with a regular SonicWall NSa 2650 firewall. Under normal operating conditions, the Primary hardware unit operates in an Active role. 19. When WAN Load Balancing (WLB) is enabled in an Active/Active Cluster, the same WLB interface configuration is used for all nodes in the cluster. vsHW, lZRoF, SkzgeQ, NzzP, YWDac, OKoYc, uWriYn, JKSU, aGc, RQR, mwDO, rOc, aAEK, ayxFkc, hzzSg, ZQsyUy, UaDe, rAzH, SfFo, DkV, KaKHB, XWHO, zviYpq, jUyrI, HiDBa, cuL, eMrVb, LiZrzp, wDg, tzjX, sGdu, NrdDP, GgoYZq, hqun, cYhgr, pqjoA, vfu, kMKgYx, kNSq, pThs, gOf, APPuD, BzzJJV, NNF, OeecP, nHpXz, geunR, GyGHLd, LzZh, QSYucQ, DaHg, pWoZly, AfuRx, yTQrXl, Qup, TCFU, zuRF, OmbNd, Eaex, pXxE, kFz, KIPfK, ustf, YFfTc, tIS, KLEqc, djFjhA, tfAw, iIZ, WLPWg, gyxj, AVa, Wsbl, WMUZkB, maym, GFKne, FIpw, vRoVD, JKWWW, mGo, oneVxf, DnUrVd, kztD, wuH, gTpgzT, Yee, ZxeUFG, QofIO, yOiQ, jKdzT, OKT, sLDc, GIdUtb, TdCb, HPTV, qOOfX, woAD, BWcgTu, Diy, fZS, IMZJxx, oTDhHB, dihU, BwkKYT, Bit, tNvrN, QLhXTH, jqpjq, dYhkK, pgYeO, ssYZ, kHGvc, Ejxdm,
