Hi David -

You might want to look into a router specific distro like Vyatta.  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
