While RFC 768 appears to reserve *source* port zero to mean "don't reply to this datagram", I don't see any similar statement for destination port zero. /--------[ RFC 768 ] | Source Port is an optional field, when meaningful, it indicates the port | of the sending process, and may be assumed to be the port to which a | reply should be addressed in the absence of any other information.
