I’m looking to route traffic between networks sitting two levels deep to a PIX firewall. My example assumes ICMP is permitted in and out of the PIX. The question is about the routing limitations of a PIX.

1.0.0.0/24<>RouterA<>2.0.0.0/24<>PIX<>3.0.0.0/24<>RouterB<>4.0.0.0/24

2.0.0.0 Inside Interface

3.0.0.0 Outside Interface

To PING from 1.0.0.0 to 4.0.0.0 I added:
route outside 4.0.0.0 255.255.255.0 RouterB IP

To PING from 4.0.0.0 to 1.0.0.0 I added:
route inside 1.0.0.0 255.255.255.0 RouterA IP

Is this correct as long as the routers have the correct routes established?
