Basically, I mean is it safe to rename the computer name and the workgroup of the computer behind 
the router, because the router is presenting that info to the internet now?  Currently, both the router 
and the computer have the same name  / workgroup, and I just wanted to make sure that I could 
rename the computer (which resolves via DHCP) - I think I can - just wanted to make sure...

Does RedHat's default server install include a GUI?  Seeing as it is my only full time linux computer, 
I would like it to have the gui in case I actually wanted to use it for other things, like getting my mail 
in Kmail, or participating in IRC.  I guess ideally it would be better to use 2 seperate computers, but 
my wife would shoot me!  :-)

That was pretty much my question.  Using your example, if you have a computer called gw, is that 
the localhost name, or the localdomain name?  I am trying to get a feel for what that looks like.  For 
gw, what does it look like in the localhost.localdomain format?  Do all the computers that you have 
share the same localdomain?

I only gave the workgroup example because that's what I am familiar with...  How do you connect 
from one computer to another computer on the internal network?

I only mentioned the DMZ because the manual said it is a way of letting the computer be accessible 
to the outside world.  I think I can just use port forwarding of port 80 to let people get to the web site 
that I want to host...

Without the picture, my setup is basically: the cable modem goes into the wan port on the router.  
Port 4 on the router connects to the Win98 computer (with dual boot slack8.0).  Port 3 on the router 
will connect to the linux computer we are talking about (the RedHat server for the website) once I 
run the cable.  Port 2 on the router will be used for my WinME laptop, on the rare occasions I need 
to connect to the internet for anything.  Port 1 is not being used for anything (and my wife says it 
better stay that way!  :-)

That's good!  :-)
