Media praise for The Book of PF

"This book should be in any well-stocked bookshelf."
-- Axel Gruner, BSDWiki

"All in all, this book is very readable and a must-have resource for anyone who deals with firewall configurations. If you've heard good things about PF and have been thinking of giving it a go, this book is definitely for you. Start at the beginning and before you know it you'll be through the book and quite the PF guru. Even if you're already a PF guru, this is still a good book to keep on the shelf to refer to in thorny situations or to lend to colleagues."
-- Dru Lavigne, Technical Writer
