I am setting up a VPN between two offices. Each office has a T1, 1700 series router, and a PIX firewall (I believe they are 515 series). Each of the firewalls has a public IP on the outside interface and a NAT IP on the inside interface. Once I setup the VPN how do I make the PIX "route" the internal traffic (how does PIX A know what the private adderss is of PIX B)?
I have this problem too.
