Firewalling with PF manuscript

Peter N. M. Hansteen released an updated version of the »Firewalling with PF manuscript«.

This lecture is about firewalls and related functions, starting from a little theory along with a number of examples of filtering (from real life with the OpenBSD project’s Packet Filter – PF) and other network traffic directing. He discusses PF firewall configuration on various BSDs – FreeBSD, OpenBSD and NetBSD. The lecture is a work in progress and will be updated periodically.
