I have a 1841 that I want to use to bridge my T1 over to ethernet so I can assign my T1 IP address to the outside interface of my pix.
I have the 1841 with an Internal CSU and a crossover cable going from FA0/0 to the Pix outside. I have disabled ip routing on the 1841 and set both s0/0/0 and fa0/0 to bridge group 1. I have set the bridging protocol to ieee but I cannot ping from the PIX. Is what I'm trying to setup possible?
Thank you for the reply. I do have ICMP permitted on the pix I actually had it in use on a cable modem before this T1 went in place. I think the problem I have is in the bridging on the router. I see that I am getting RX packets but no TX packets when I do a 'sho bridge'
Traffic local to the outside subnet of the PIX will only be getting bridged. If you want to ping and route IP on the outside router then you need to configure something called IRB (Integrated Routing & Bridging).
Here's a couple of links that can help you with that.
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?
