Adventures in Firewalling
by Bill Moran

I recently installed what I would consider a fairly complex firewall. While there are already numerous articles, tutorials and the like available with regard to firewalls, this is a subject that I don't really feel can be covered too much.

This provides transparency and allows our firewall, which we maintain on the bridge, to securely filter incoming packets and forward them without modification to the internal destination. This guide walks through two typical home network connection setups (ADSL and cable modem) using OpenBSD 2.8. Read More

Adventures in BSD: BSD in a Microsoft Office
by Joe Warner

After tinkering with FreeBSD at home for a while, amidst all the noise and distractions that go with a family setting, I decided to see if I could install it on an unused pc at work.
