The "minimum" is what you can get FreeBSD to run on, If you can can get 
FreeBSD working on a 386 then that is the minimum but for practicality a 
486 is the absolute minimum. As far as the minimun amount of disk space 
is conserned the same thing as above goes, here is a FreeBSD router 
project that works on as little as 5MB: . Same 
thing goes for RAM and obviously you need to have at least two Network 
Interface Cards unless you wanted to route all traffic to /dev/null.

You would plug them into a switch not a hub.... if you did that then the 
router would be the least of your problems as the bottleneck is the hub now.
