LOL I don't think so! TCP packets do not have enough bits allocated for
port numbers to support this, so 492716 is *unaddressable* over TCP. I
think the only explanation for successful behaviour would be some sort
of overflow or truncation behaviour. What is the value of 492716 if you
truncate it to 16 bits? 33964? I suggest that if you are communicating
over TCP port "492716", you are in reality using TCP port "33964". Same
with UDP ports, I'm sure.
