It differs from a bridge in that *it requires a chunk of routable IP space
to put behind it*, and a route to go there.  For the specific situation
I posited, a consumer connection, you can get a static IP, but you *will
not* get routable space; you have to go to a business connection for that,
at 2-4 times the cost.
