foaf (Firewall On A Floppy) – a very small OpenBSD based distribution which provides a firewall on one floppy disk.
This allows you to create a firewall that is based on a floppy (hence the name), and you can build it from a separate source tree. Edit the files in [foaf/config] to configure for your system. Make sure you at least edit [foaf/config/etc/pf.conf] because it has bogus entries for IP addresses, and blocks everything. Right now it is mainly for invisible bridging firewalls, but I (developer) plan to expand it to be a routing firewall.
If your desired network device (or other such device) isn’t supported on the default kernel config (FIREWALL), feel free to add your own. Take out devices that you don’t use.
The project developer is Peter Hessler, and the foaf is released under the MIT License.
