Which firewall ?

Netveda safety.net running fine with the trial version.

 

I'm comfortable with using just the NAT of a router myself, don't really need the one built into XP, but it doesn't bother me so I leave it on. I only have a need to prevent the outside from coming in. I'm careful with what I do on my computers at home, no e-mail clients, certainly no system-screwing up P2P warez downloading software, I only hit a few tech websites, so I don't want the bother of some annoying, nagging 3rd party software firewall to bog down my system. I use Opera for my browser, and NOD32 antivirus, all windows updates, and a fairly secured system.
