This problem is usually solvable by some tcpdump and ping detective work. First, establish that your machines can ping the router, and vice versa. Then, ping the router to your internet gateway. Then, ping the gateway from the intranet. If no success, use tcpdump on both your router's NIC's to see where the packets are being stopped. It may be bad routing, or maybe you haven't turned on ip forwarding, or maybe it is your firewall. Sometimes looking at the arp table (arp -n) will give you insight. Joel
