SV: port 256/257 and firewall-1

Well, correct me if I´m wrong but doesn´t FW-1 check the source adress against it table of permitted GUI clients?
If the packet comes from a non-permitted client it just discards it.
But, I could be wrong.

As I said, limited testing.  I've tested out of band data and a few fuzz
tests.  FW-1 appears to simply ignore everything that isn't strictly
what it wants.  Clearly, I don't have the definitive answer on this
subject.  Perhaps someone with more time could take this ball and report
their results?
