Ok, first I presume your windows & linux boxes are on separate lan's,
or is there a connection between them?
Looking at some docs for the Netopia-3346N found at
http://www.netopia.com/support/resources/option_3346n.html it looks
like it's a pretty standard router. If so, then it shouldn't be too
difficult to setup as the router should support what you need.
By the looks of things it's probably going to be one of:
1 Configure the router to use static addressing
2 Configure the router to use nat then IP Map the static IP's to your
internal IP's
3 Configure a static route from your Windows network to the Linux network
#'s 2 & 3 are probably the better. #3 would be needed if you have 2
separate networks (ie different IP address networks like 192.168.1.x &
192.168.2.x etc) but you would need to setup a router between them
(use a Linux box for this, and use 2 NIC's if the cabling is
separate).
