Jeff, I think we are on to something here. I added a static route on the 192.168.1.1 router to the 192.168.1.224 with the gateway address equal to the eth1 IP address on the firewall. I can now ping 192.168.1.1 from behind the firewall but I still can't ping 209.73.186.238 (yahoo) from behind the firewall. I can ping yahoo from the firewall. Any other thoughts?

The router or the firewall? It looks like your router doesn't know how to get back to the 192.168.202.x network. If you add a static route on your router that tells it to send traffic destined for the 192.168.202.x network to the 192.168.1.224 interface on the firewall box I think it will start working for you. /jft _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos
