"Hello there.
I have ported pf to FreeBSD 5.0 Currently it works well, though many nice features of pf not tested. I have ported to make FreeBSD users know there is an another excellent stateful packet filter with BSD license. URL is the following.

Thanks."

Wow, this is pretty cool. I know that PF had been ported to NetBSD as well (as an LKM, without ALTQ), but I didn't know about this effort for FreeBSD. It's good to see that people are mixing up their options, and maybe they can contribute something back to OpenBSD's PF.

the other two brothers can enjoy, evaluate or criticize OpenBSD's proprietary firewall now!

GREAT!
