Eric,
Take the hub out of the equation by using a cross-over cable to connect your firewall
directly to the router terminating your T1. The hub's not necessary unless you want a
DMZ at some time. Also, check the IP addresses and subnet masks for both cards to
ensure they specify different subnets.

Here is the way things are set up on the network. There is a T-1 line
coming into the office. This connects into a 3-Com 8 port hub that
connects to another 3-Com 8 port hub. There are currently 3 Linux boxes,
3 WinNT boxes, and 1 Win98 computers connected.
I knew that I had to install a firewall and wanted to use a Linux box
running ipfwadm. Once I installed Redhat 5.2, I then installed ipfwadm.
There are two network cards in the computer. Network card 1 is plugged
into the "firewall" hub. This is a 4 port 3-Com hub that only the T-1
and the firewall is connected to. The second network card is plugged
into the internal network.
When I do this, the "firewall" hub has no lights for the firewall. But
if I connect to the internal network everything is fine.
Help!
Eric
