Nokio,

Yes Comcast is full of it. I use the same ISP and the OS you use is 
completely irrelevant. Every modern OS has a TCP/IP stack, if youve got an 
OS that recognizes the NIC then you can get on the internet.

Your Redhat box can be used as a router, quite easily I might add. The RH 
8.0 install even offers a choice to something of this effect. Like 'this 
box is going to be a router' type thing. Networking is very complex, can 
be confusing. Your going to have to setup NAT on this box as well. NAT 
will allow the private IP addresses you assign the XP and other RH box to 
use the IP address your ISP assigns your router box. (you might have to 
read a bit on NAT and routing). You can use IP tables for this and just 
create static routes for the IP address on your internal boxes. Securing 
the box can be done with IPTABLES as well. http://www.netfilter.org/
My honest advice to you would be to buy a 40$ home DSL/CABLE router, its 
much more secure and easier then securing a first time RedHat install 
seeing as your a bit new to it. 
Hope that helps even a little bit.

Chris
