The BSDwall Project

The purpose of the BSDwall project is to make it easy for people of minimal technical ability (and, minimal hardware) to set up a useful firewall for a home or small business, using the *BSD Free Software operating systems.

If configuration files and documentation can be considered "software" then the BSDwall project is also a Free Software project. Subject to crediting BSDwall, you may freely use and redistribute information found throughout this site, and use modified versions in commercial products, as with the generally accepted usage of FreeBSD, NetBSD and OpenBSD.

The config files shown within this site are taken from the OpenBSD project and are subject to its license, see Any wholly original material at this site, including the "bsdwall" Perl script and all documentation, are provided under a license identical to the Berkeley License used by OpenBSD.


There is no need for configurations of a BSD operating system to be restricted to any hardware architecture or any of the three popular BSD projects.

However, at present, the provided material has only been created and tested with Intel hardware, because of its availability, using OpenBSD, because it has the strongest focus on security. At present, bsdwall uses OpenBSD 3.8.
