No, I really don't need it to route anything. But the port is there, and I thought I should know how to make it work. 1. It did need the crossover cable. 2. I didn't have the route right from the firewall to the router. I made the router (wan side) 192.168.1.2, 192.168.2.1 lan side. Then I added the route on the firewall: 192.168.2.0 gw 192.168.1.2 eth1. It works. I'm very please. And thank you for your quick response.
