After looking at the shorewall diagrams I wonder if I could not 
reconfigure my system.  Presently I have a Linksys WET54G wireless 
bridge feeding this computer[box1] via eth0 and an old Linksys EZXS55W 
5-port ethernet switch connected to eth1 and some other computers 
including the XP computer [box5]. 

What if I move the switch between the wireless bridge and this computer 
[box1, eth0]. It seems I should be able to tie the XP box5 into one of 
the four remaining ethernet ports on the switch and get both a route to 
the internet and between boxes via Samba.  Before embarking on that 
effort I would like more knowledgeable comment however.  I'm probably 
getting in over my head but I usually manage to muddle through such 
things eventually if they can be done.

I have been using Firestarter to setup the firewall for some time but 
could probably manage with Shorewall if necessary.

Any comment appreciated.
