Is it wired like a etherent host port, or like a hub/switch port? If it would ordinarily plug into a cable/dsl modem (hub) it's probably wired like a host, and since the eth card in your is also a host port, maybe you need a crossover ethernet cable? > The firewall is a Linux machine configured with ip forwarding.
