We have already talked in this blog about IPCop, a GNU / Linux distribution aimed at making your network more secure, you will also know m0n0wall, the latter based on FreeBSD. Well, now we present you pfSense, a FreeBSD-based system to act as Firewall and Router. It is open source and can be installed on many computers.
Its configuration web interface is very reminiscent of IPCop or m0n0wall. The project was started in 2004 by Chris Buechler and Ullrich Scott as a fork or derivative of m0n0wall. Its focus was on PC and server installations, as opposed to m0n0wall, which is more optimized for low-resource computers and embedded systems.
With pfSense you can have a free and very secure firewall for your network, maintained by the BSD Perimeter development team. The truth is that it has little to envy other business payment solutions such as those from Cisco, SonicWall or Jupiter. And if you are interested you just have to download it from the official site.
Now they have released pfSense 2.2.2 version with many improvements. Among the improvements are the functionalities, correction of security flaws and updates in the included packages. One of the solved security flaws affects the IPv6 module, the other affects the OpenSSL library, which has had the latest update to patch vulnerabilities that some could be used to carry out DoS attacks.
