PF is a complete, full-featured firewall that has optional support for ALTQ (Alternate Queuing), which provides Quality of Service ( QoS ). The pf packet filter was developed for OpenBSD but is now included in FreeBSD, which is where I've used it. Having it run at boot and the like is covered in the various documents, however I'll quickly run through the steps for FreeBSD.
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. PF was originally developed by Daniel Hartmeier and is now maintained and developed by Daniel and the rest of the OpenBSD team.
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, as well PF has been a part of the GENERIC kernel since OpenBSD 3.0. PF was originally developed by Daniel Hartmeier and is now maintained and OpenBSD PF: Address Pools and Load Balancing NAT Address Pool An address pool can be used as the translation address in nat-to rules.
