Introduction to pfSense-An Open Source Firewall and Router Platform


What Is pfSense?

pfSense is a free, customized distribution of FreeBSD that can turn an old computer into a full featured router and firewall.

pfSense is very flexible and can easily be adapted to numerous applications ranging from a home router to a firewall for a large corporate network. pfSense is easy to install and maintain offering a very useful web based user interface. pfSense includes many features that are often only found in expensive commercial routers.


Popular Uses for pfSense

  • LAN/WAN Router
  • Internet Cafes
  • Wireless Hotspot (Captive Portal)
  • VPN Router
  • Firewall
  • DHCP / DNS Server
  • Wireless Access Point
  • Transparent Squid Proxy Server
  • Multi Wan Router or Load Balancer
  • DNS Blacklist
  • Port Forwarding / NAT (Network Address Translation)

Why Use pfSense Instead of Another Router?

pfSense is fast, free, and stable; offering tons of great features.

If you have an existing router that doesn't offer the features or performance you need, pfSense is a great choice to replace it with. Offering complete control of the hardware, you can customize your pfSense system with the components you want.

By using pfSense you can save a ton of money without compromising on features.


Getting started

In order to setup your own pfSense router, you'll need an old computer with at least two network cards installed. pfSense can also run on a number of embedded devices.


Embedded Installation

pfSense can also be installed on several different embedded platforms such as PC-Engines, Soekris, Alix, and others.

Embedded installs are a good option if you are looking to create a small, quiet, low power appliance to run your network. If you are a consultant it's going to look a lot more professional to set up an embedded pfSense device for a customer instead of an old PC.

If you decide to do your install on an embedded device be sure to download the embedded version of pfSense. The embedded release is designed to be installed on hardware that uses compact flash for storage. The embedded platform has special tweaks that will greatly extend the life of the storage media.
