I have a situation where I would like to perform the NAT/PAT process on addresses going through a PIX that are going to traverse a point to point IPSEC tunnel.
The reason that I want to do this is because the source subnet that I am originating my Point to point tunnel from (10.1.1.0 for example) already exists on the destination network(s) across the point to point tunnel. This subnet is a routed subnet on the destination of my point to point tunnel. I believe that my sessions would get routed and never return back to me.
Is it possible to perform NAT/PAT prior to sending IPSEC sessions with original addresses across the point to point tunnel ?
