I apologize because this doesn't answer your question but proposes an 
alternative arrangment that, I believe, would be easier to configure.

I don't know the physical arrangement of your devices (in your home or office), 
but my arrangement (and most arrangements I've seen) are a little different and 
maybe you want to try an arrangment more like this:

Put your router immediately after the AT&T modem, then (assuming there are 
multiple ethernet ports on the router), put your Linux box on one eth port and 
the Windows box on another.  (That would require 3 ports on the router.)

If you don't have 3 ports on the router, consider getting a switch to place 
after the router, and put the Linux and Windows boxes on 2 separate outputs 
from the switch.

Either of these is a much more standard arrangement, and I have very little 
trouble with any of this.  (The troubles I have had are not relevant to the 
arrangement--things like Earthlink / Verizon outages and dealing with their 
customer non-support, an anomaly in how a Westell modem worked (now using a 
ZyXel), and difficulties in understanding and configuring QOS (primarily for 
VOIP).)
