FTD Route Based VPN question

benolyndav — Wed, 14 Jan 2026 14:05:11 GMT

I have a static Route Based VPN and am wondering if I create a loopback interface on the FTD is there a way to allow this IP over the VPN to test the VPN or generate some traffic from the FTD across the VPN ??

Thanks

@benolyndav as long as the peer has a route over the VPN to that loopback IP address and firewall rules that should work. I assume you aren't using the loopback as the tunnel source?

@Rob Ingram No not using Loopback as tunnel source

Thanks

@benolyndav thats fine then. On the remote peer just create a static route pointing to your tunnel IP via the tunnel interface. You will need to permit the traffic in the firewall rules.
