Windows built-in packet filter

[delerious]

I just discovered that Windows 2000 and XP have a built-in packet filter (under Local Security Policy -> IP Security Policies). Anyone use this? From what I can tell it seems to be pretty basic, so I think I'll stick with CHX.

Yes, IPSEC is very simple and basic, and nowhere even close to something like CHX. Stick with CHX as it's far more versatile and functional.
