pfSense: The Definitive Guide by Christopher M. Buechler and Jim Pingle is published by Reed Media. Amazon.com just posted my five star review of the book. I was pleased to see coverage of many issues related to network security and firewall design and operation. For me, these features elevated the entire book to five star status. If you’re interested in learning how pf Sense can help your organization, pTDG is the right book. It is available now.”]
