Now that Ralph explained my ignorance to me, I think what you'll need is a second interface on the PIX, though you'd probably be better off using a router if available. A PIX doesn't route - that's the first thing. The second thing is that if both of your VPNs are coming over the Internet into the PIX on the third network via that PIX's outside interface, what you're trying to do will never work. The PIX just sees the traffic from both networks coming in on the same interface and assumes the traffic is spoofed. One fix would be to add an interface to your PIX and give it access to the Internet. One of those VPNs would then terminate on that interface. Because both networks would then be local to the PIX it would pass the traffic. I'm not sure how your friend would be doing any better with the same setup and three PIXes - so long as the two are still being terminated on that one PIX interface. If I'm wrong, I'm sure Ralph or someone will let me know - and I'd be curious about the security risks involved in using a second PIX interface like this, if any.

Ralph: A friend told me that his vpn peers can have communication, but he has pix as tunnel endponints on the 2 sites, (i have routers), does apply here what you said? "PIX will not send traffic out the same interface it came in on" or using pix as endpoint is different?
