OpenBSDs PF is indeed the worlds finest software based firewall, I'll be the first to say. I think Linux should throw out IP tables and go for a PF port, but I digress.

I haven't tried mitigating a big DDoS with PF, and I don't know if it would fare any better once it has say 50k individual IPs to block. But to me that is kind of beside the point. If I am not mistaken, a well written nginx module would be the immensely helpful when faced with the kind of DDoS I had on me last week.

If I can't find anyone interested in writing it I might have a whack at it myself next time I get some spare time.
