If you already have a hub, you can get the Linksys BEFSR11 - without the
4-port piece - from Amazon for $106. If it works as a FW router, you can 
always layer your FW with Linux as a Bastion Host, even put an internal
(ether-to-ether) router between it & your LAN hub. Very hard to bust.
5 years ago it cost about $3K for a bilevel router to do this @ only
10MBPS ehter speed!
