I have a design need. I have a cisco 1700 series router at our main office that has two WIC's installed in it. One interface has a frame relay connection on it with two sub interfaces. One of the sub interfaces connects to a remote office and the other to our ISP. The other WIC is connected to a remote office vis a point to point T1. What I'm needing to do is install a pix firewall behind this 1700 router so that I can connect client VPN sessions to it. My question is what kind of design should I use in oder to terminate remote peers on the pix but still be able to have NAT for the remote locations? Can this be done?
