I have a peer that I send backups to. They have two sites that they use for the backups. One is a primary and one is a secondary disaster site. The tunnel is always initiated from my side. They have a FQDN that is supposed to be used for the peer address so when they do disaster testing it automatically fails over to the secondary site. With FTD version 7.0.0 you can set up a backup IP address but this does not seem to work as expected and this failed and required manual intervention. I am trying to use the FQDN for this but it requires an IP for the extranet peer. Is there a way to configure this so that I can use the FQDN instead of the IP address? Maybe something like setting up a local loopback that can be used for the extranet peer then point to an FQDN? Using an FQDN for a remote peer is a common solution and I am baffled why this wouldn't be something that is available for this configuration.
