So a couple of weeks ago I was charged with setting up a firewall for a business. I pretty much knew which operating system I wanted to use because of stability (one of the BSD range). When I eventually got round to loading a system though, I was blitzed by my 4 year absense to the OS. I couldn't make head nor tail of what ports I needed, or how to configure the components I wanted. I knew that considering that I wouldn't be the only admin, I would likely require to get a GUI setup on the box because their other admin(s) might not be so adventurous with just a commandline. I spent a couple of days attempting to load the system and it got closer and closer to the deadline I'd offered. A sudden air of panic occured that I wouldn't get it implimented on time. With that one instance I looked to how long the install was taking and questioned "There has to be a quick fix for what I'm after. Perhaps an already configured kernel? perhaps a live CD?" With a quick search, I found PFSense a Freebsd based Firewall that could be loaded on a Live disc. My hours of pratting around trying to get a system fully configured went from days (since the box I was using was low speed) to a couple of hours tops. In fact it seems the development team has done awsome job on the project in regards to making it easy to configure and there are a few additional packages that can be added to make the firewall server do so much more. I mention it here because I'm obviously pretty impressed with this build, but do any of you know of any other firewall servers out there and are you equally as impressed?
