RE: [PLUG] cable modem and MAC

Thats all fine 

modem ---> linux router ----X0----> other machine
                 |
                 |
                 ---wireless card----> wireless machine

You could get a cheap switch to replace your xo cable with in case you want
to plug more machines on to you network.

Also when you setup IPtables i would suggest taking a look at a program
called fwbuilder Its a helpful interface for keeping your rules straight,
though it does make very messy looking chains.

I'm glad you asked this question.  I need another NIC!  I didn't realize 
it until I went to make a connection list.

I will be using my RedHat 9.0 PC as a router and workstation.  Nothing 
unusual.  Here's my initial arrangement:

modem
GNU/Linux PC
-- crossover cable to second PC
-- wireless card to wireless laptop
