The OpenBSD Packet Filter FAQ

Tuesday, 6 May 2003, 10:41 AM EST

Packet Filter (from here on referred to as PF) is OpenBSD's system for filtering TCP/IP traffic and doing Network Address Translation. PF is also capable of normalizing and conditioning TCP/IP traffic and providing bandwidth control and packet prioritization. PF has been a part of the GENERIC OpenBSD kernel since OpenBSD 3.0. Previous OpenBSD releases used a different firewall/NAT package which is no longer supported.

This set of documents is intended as a general introduction to the PF system as run on OpenBSD. It is intended to be used as a supplement to the man pages, not as a replacement for them. This document does not cover all of PF's features and may not be as up to date as the man pages are.
