This will be configured using a Policy-Based VPN (not Route-Based). The IKE negotiation use the certificate method instead of the preshared key method. Ensure that you modify the remote endpoint to use the complementary Even if you choose a non-null option, the integrity hash is ignored for these encryption standards. Each end of the connection specifies the certificate for the local end of the connection; you do not specify is no connection through the configured interface, you can leave off the Encrypt and Click But, if you need to provide site-to-site VPN services to the 192.168.1.0/24 network, You can configure only point-to-point VPN connections using FDM.
