The community edition is free or you can go the paid support route. Vyatta will give you a much more robust router capability with a more maintainable configuration than trying to set this up by hand using IP tables. It also supports routing protocols like OSPF that make a lot more sense in the type of application you're looking at. Cheers, Dave
