Well, no. By default, Shaw gives out one IP address per cable modem, so if you change the connected device from the original router you tried, to something else, it ignores the new device. Sometimes powering down the cable modem (and waiting... hours? Days?) helps, but the better solution is to call Shaw Internet tech support and tell them you want your free second IP address activated.
I only need one address. I just need the NIC to get it. I was trying to bypass the firewall to see if that's where the problem was.
I am guessing the firewall is NOT the problem: 1) I can connect on another machine on the LAN that should be handled the same way by the firewall. 2) The second app used to work with the same firewall on the first machine.
Could a NIC 'partly' fail so that it can't accept an address by DHCP and will fail with some connections but not others?
You may still have to power down and up the cable modem after they do this. Shaw provides all Internet users with two IP addresses, but the second one has to be activated on request.
After that, you can try plugging in your computer or other device to the cable modem to do tests - although I'd be loathe to do that with a Windows 2000 machine.

I have a home LAN that uses a iptables firewall running on FC 4 on my gateway machine.

I plugged my Win2K machine directly to the cable modem and configured it to connect by DHCP. I could not get an address for it. Shaw believes the modem is working and trying to assign an address.

It is suspicious that the NIC would not configure when plugged to the cable modem - but everything else works. I can browse the web and get my mail.
Is this consistent with a NIC failure? could it be something else?
