Building Firewalls with OpenBSD and PF
Jacek Artymiak
I have used PFCTL for a couple of years, but have needed a book for reference that was easy to understand. I found this book to be exactly that. I recommend this book to anyone that needs a good reference on pfctl firewall. I had some holes in my knowledge/understanding of pfctl that this book readily filled. Much appreciated, and will be used a lot.
