VPN unknown Interface FW/Routes

Whenever my VPN Interface loses connection then the FW and route rules switch to ‘unknown’ interface.
I have to manually reset the rules to the correct interface (ex; lt2p-offsite).

Is there way to have have the FW and Route automatically setup the correct interface after loss of connectivity from peer?

Yep, create static binding(s) for the user.

Static interfaces are added administratively if there is a need to reference the particular interface name (in firewall rules or elsewhere) created for the particular user.
