What Windows 7 Firewall are you using?

[XxDeadlyxX]

I use Comodo firewall with Vista, does it work with Windows 7? If not, what is a good alternative?

A good alternative is the one it comes with. I mean really, are 3rd party firewalls needed anymore? The built in one seems fine, especially when paired with the firewall in most modem/routers, I also run IPCop, but that's beside the point. ::p:

Installed comodo, it runs but the firewall doesnt seem to be working. So i scrapped it and im using W7's bitdefender and windows firewall for the time being.

Any free W7 supported firewall software out there?
