In that case you're only binding to a single address so the
BindAddress key will work.  OTOH A firewall should not have server
software running on it.  CVSNT is not secure enough for that kind of
thing (at least it's never been validated as secure, which virtually
guarantees that some kind of hole exists somewhere).
