I have been looking around lately at all the old hardware I have lying around and thought what could I do with it all? Media center? Web server? Hardware Firewall perhaps? Then I came across Untangle Linux Firewall and thought why not give this a try!! Next thought was why install on the old hardware and increase my energy costs when I can install it on Virtualbox on my main Linux server instead? So I have installed Untangle Linux Firewall on Virtualbox running on a Linux Mint 10 File and Print Server and below will outline how I did it.
