Great job on the write up. Firestarter is definitely easy to use, and seems popular too. A good starter personal firewall.
It's great for a personal firewall, but I wouldn't recommend it for the corporate firewall. There are plenty of simple options available for a better stand-alone firewall, such as IPCop, SmoothWall Express, Pfsense, etc., that all have great web-based interfaces, and offer many more features. »

Agreed. When I'm done building a server, and it's ready for use, I always boot it with SystemRescueCD live cd, and backup the partition table and partitions (Partimage) to a writable DVD. Takes about an hour.
I can build a new replacement server in about an hour, online and ready for data restore. »
