Any machine directly hardwired to the outside world needs the protection. If
your secondary machines are only talking to the primary machine on a local net
(with non-global addresses), then they should be OK. If all the machines are
connected to your DSL line with DSL modems, then they all need some kind of
protection (though again, this could just consist of turning all shares off
and blocking free ports).
The Sonic Wall acts just like a primary machine in this regard, i.e., the
other machines connect to *it* rather than to the DSL line.
