This guide was written for Linksys, Netgear, and D-link users with no firewall or router experience. No experience is needed with FreeBSD or GNU/Linux to install and run pfSense. When you are finished, management of pfSense will be from a web interface just like any of the SOHO firewall/router appliances.pfSense is a web-based firewall project that is similar, in terms of functionality, to the software in firewall appliances sold by Linksys, Netgear and D-Link. pfSense covers all the basic requirements offered by those appliances but offers so much more--in fact, it is really in a class by itself since it would be very difficult to find a commercial alternative that would provide what pfSense has to offer (or, anything cheaper than $2,000–$5,000).As mentioned above, in this article I will explain how to setup the pfSense firewall with one WAN interface, one LAN interface and one Opt1-WiFi Interface. This set-up allows you to offer wireless Internet to the surrounding community. The WiFi subnet will not be able to access the LAN: it will be able to connect to the Internet only. You can choose to eliminate the Opt1-WiFi setup: this will leave you with a firewall more similar to the "conventional"
appliances.One of the very unique uses for your new firewall could be to offer wireless Internet to your neighbors at a reduced costOne of the very unique uses for your new firewall could be to offer wireless Internet to your neighbors at a reduced cost. This connection can be via an encrypted access point, where the network key is only given to approved users, or an open access point where you control access to the Internet with the captive portal function built in to pfSense. A portal landing page will be presented whenever a user tries to connect to the Internet at the beginning of the session. Each user will need to have their user name and password entered into the firewall in advance of the first connection.
There are many advanced features that pfSense can offer with one-click installation which are listed at the end of this article. See the pfSense's web site. There is an active user forum and an pfSense Wiki.
