Ah ... that's different. :-)
NAT provides a fair amount of protection for the computers behind the
router. In theory the presence of NAT means that the computer(s) behind the
router are invisible to the Internet. In practice this may depend on the
configuration of the router, especially if it's forwarding ports to any PC
inside the NAT barrier.
Adding a firewall to the network setup will provide further protection - or
at least alert you if unwanted traffic is getting to your PC. If you add a
third-party firewall (as opposed to the built-in XP firewall) you will get
both incoming and outgoing alerts and protection - which could come in handy
if you have let something inside that's establishing a connection you don't
want to the outside world.
