This book, and the pfSense® project itself, would not be possible without a great team of developers, contributors, corporate supporters, and a wonderful community. The project has received code contributions from more than 200 people. Hundreds have contributed financially with hardware and other needed resources. Thousands more have done their part supporting the project by helping others on the mailing list, forum, and other platforms.

Personal Acknowledgements

From Chris

I must give my wife thanks and considerable credit for the completion of this book and the success of the project in general. This book and the project have led to countless long days, nights, and months without a day’s break, and her support has been crucial.

I would also like to thank the many companies who have purchased our support and reseller subscriptions allowing me to make the jump to working full time on the project in early 2009.

I must also thank Jim for jumping in on this book and providing considerable help in completing it. It’s been two years in the making, and far more work than I had imagined. It may have been obsolete before it got finished if it weren’t for his assistance over the past several months. Also, thanks to Jeremy Reed, our editor and publisher, for his assistance with the book.

Lastly, my thanks to everyone who has contributed to the pfSense project in any fashion, especially the developers who have given huge amounts of time to the project over the past nine years.

From Jim

I would like to thank my wife and son, who put up with me throughout my participation in the writing process for not only the first book, but continued revisions over the years. Without them, I would have gone crazy a long time ago.

I would also like to thank Rick Yaney of HPC Internet Services, for being supportive of pfSense, FreeBSD, and Open Source software in general.

The entire pfSense community is deserving of even more thanks as well, it is the best and most supportive group of Open Source software users and contributors I have ever encountered.
