[quote="Full Metal Jacket":7d959]i heard zonealarm is great, but is xp firewall worth having on....? is it any good...not the best..but anygood[/quote:7d959]

....that depends on how you have your computer configured. If you have a stand alone computer, use the WinXP firewall along with another type like "ZoneAlarm" or "BlackIce".
If you're hooked up through a router, you can disable the WinXP firewall since the router has a built in firewall thats better. Also, if you host through a router, you'll have to disable the WinXP firewall.
