Which firewall for Windows XP Pro x64?

Just wanted to know which firewall are you guys using with Windows Xp Professional x64.

I am using NOD32 as the antivirus and I am looking only for the firewall.

am using nod32 & xp default firewall. not had any probs yet.

COMODO FW no problem so far and it’s FREE (I have XP Pro SP2 32)

^^ comodo does not work yet on x64 systems. i tried ghost firewall, but removed it in under 1 minute - worst firewall i’ve seen till now.

imo the built in windows firewall is good enuf.

Yup, comodo does not work with x64. Have to use the windows native firewall.
