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!
