I have a DS3 ATM port with PVC configured that attaches to the router on my private network. I would like to add a second PVC for Internet connectivity, but I want to place the second PVC on a router that is attached to the firewall network. What I would like to do it place an ATM switch in front of the routers and have the ATM switch map the PVCs to the respective routers, that way one pvc goes to the private network and the other pvc goes to the Internet network. Is it to accomplish this and what CISCO ATM box would have to purchased to do this?
