Can a Cisco PIX Fiewall be used as a router? I have 2 Cisco PIX 525 Firewalls and I don't have any _router_. They are running version 7.2. Can i use that as a Layer 3 router and use its interfaces for different subnets?

In the immortal words of Cisco (circa 1999), " _the PIX is a firewall, not a router_ "

That said, it can be used as a router. But you're better off using _anything_ else, as it's firewall nature is going to be a pain in the ass. (I used to do it with a PIX 520, and I hated it for all time.) If it's what you have, then it's all you have, but I cannot over emphasize how much better off you'll be with an actual _router_. (buy one, _build one_ , whatever it takes.)
