The Book of PF : A No-nonsense Guide to the OpenBSD Firewall

A solid understanding of OpenBSD's PF subsystem is a necessity for any network administrator working in a *BSD environment.

The Book of PF is a current, no-nonsense guidebook to harnessing the power of PF.

Its contents include coverage of NAT (network address translation), wireless networking, spam fighting, traffic shaping, failover provisioning, and logging.

Written for anyone who has felt lost in PF's manual pages or baffled by its massive feature set, author Peter Hansteen helps readers confidently build the high-performance, low maintenance network they need.
