I guess either I am configuring it wrong or misunderstanding bridging. Attached is the config my router has. The IP address that's normally assigned to S0/0/0 I have assigned to the outside of the PIX. (The FA0/1 on the router address is only there for management. My PIX is directly connected to FA0/0. I want the PIX to handle all the routing and the 1841 simply to pass the traffic to the T1. Do I still need IRB for this or can I use simple bridging?
Thanks for all the help!
