[MLUG] Setting up dsl

[shivers90 <EMAIL:PROTECTED>]

I am switching from dialup internet access to
CenturyTel DSL.  I am trying to figure out how to
setup up Linux for this and what hardware I will need.
 The current setup is a desktop with a modem for the
connection and an ethernet card that shares the
internet connection over a crossover cable with a
laptop computer running linux.  The desktop is running
DHCP server, NFS server, and iptables.  While the
laptop is running dhcpcd and NFS client.

My first thought is to just add another network card
to the desktop.  I believe this would only require me
to setup the DHCP client on the desktop and everything
else would work the same.  What would be the
advantages and disadvantages to using a router (wired
or wireless) to share the internet connection versus
the second network card?  If I used a router would I
need to install a firewall on the laptop also?  How
would IP addresses work and file sharing with NFS
work?
