I am setting site-to-site VPN b/t Pix and cisco router. I currently don't have a network behind the Cisco router so I cam creating a loopback interface on the router for testing. When testing, I can see tunnel build but I can not get to the lopback interface on the router from a network behind the PIX.
Question: Is it possible to use the loop back interface as interesting traffic inside the tunnel or does it have to be on a network outside the router? Thanks.
