The most common deployment of pfSense is a perimeter firewall. pfSense accommodates networks requiring mul- tiple Internet connections, multiple LAN networks, and multiple DMZ networks. BGP (Border Gateway Protocol), connection redundancy, and load balancing capabilities are configurable as well.

pfSense configured as a LAN or WAN router and perimeter firewall is a common deployment in small networks. LAN and WAN routing are separate roles in larger networks.

Firewalls, critical components of today's computer networks, effectively protect a system from most Internet security threats. They keep damage on one part of the network - such as eavesdropping, a worm program, or file damage - from spreading to the rest of the network. Without firewalls, network security problems can rage out of control, dragging more and more systems down.

This book is a practical guide to building your own firewall. It provides step-by-step explanations of how to design and install a firewall at your site and how to configure Internet services such as electronic mail, FTP, the World Wide Web, and others to work with a firewall. Firewalls are complex, though, and we can't boil everything down to simple rules. Too much depends on exactly what hardware, operating system, and networking you are using at your site, and what you want your users to be able to do and not do. We've tried to give you enough rules, examples, and resources here so you'll be able to do the rest on your own.
