How do you resolve the issue of routing interesting traffic using the same network IP on both ends of the tunnel?

With CISCO routers it's very easy. First do dual NAT and use NATed address in your crypto map interesting traffic. I have tested this and works great.

With PIX it's difficult since you can't do dual nat with PIX. Dual NAT on router solves your overlaping ip address problem. If anybody knows a way around on PIX please post it.
