Preface

pfSense is an open source distribution of FreeBSD-based firewall which provides a platform for flexible and powerful routing and firewalling. The versatility of pfSense presents us with a wide array of configuration options which, compared to other offerings, makes determining requirements a little more difficult and a lot more important. Through this book, you will see that pfSense offers numerous other alternatives to fit any environment's security needs.

This book follows a cookbook style to teach you how to use the features available with pfSense after determining your environment's security requirements. It covers everything from initial configuration of your network interfaces and pfSense services such as DHCP and Dynamic DNS to complex techniques to enable failover and load-balancing.
