You could roll your own with a spare PC and a few NIC cards, using
freebsd or linux.. any old pentium box would work, or you could use one
of the soekris boards..
I have a setup similar to this, with 3 lans, and a dsl line.. mapping to
3 static addresses on the dsl side, using freebsd, ipfw, and natd.
