No, WinXP's built-in firewall won't provided any added protection.
However.... :
If you use a router with NAT, it's still a very good idea to use a
3rd party software firewall. Like WinXP's built-in firewall,
NAT-capable routers do nothing to protect the user from him/herself
(or any "curious," over-confident teenagers in the home). Again --
and I cannot emphasize this enough -- almost all spyware and many
Trojans and worms are downloaded and installed deliberately (albeit
unknowingly) by the user. So a software firewall, such as Sygate or
ZoneAlarm, that can detect and warn the user of unauthorized out-going
traffic is an important element of protecting one's privacy and
security. (Remember: Most antivirus applications do not even scan for
or protect you from adware/spyware, because, after all, you've
installed them yourself, so you must want them there, right?)
I use both a router with NAT and Sygate Personal Firewall, even
though I generally know better than to install scumware. When it
comes to computer security and protecting my privacy, I prefer the old
"belt and suspenders" approach. In the professional IT community,
this is also known as a "layered defense." Basically, it comes down
to never, ever "putting all of your eggs in one basket."
