I have a client that has 2 T1s from 2 different providers. They use the one connection for all of their internet traffic. The other is used right now for incomming VPN connections. On both connections I have Cisco PIX 501s. What I would like to do is set a router (Cisco or similar) on the inside of the PIXs. I would like to then set all the workstations to use the router as the default gateway. I would set the router to continue to use the primary internet connection as it is now but would gain the ability to log in to the router and change the default route to the other connection in the event of an outage. Would this work? I am using PAT/NAT on both PIXs. My current LAN is flat on a 255.255.255.0 subnet.
