***An incoming IPv6 packet MUST BE REJECTED if its destination port is a well known or registered port that has not been authorized for IPv4 port forwarding.***There is no agreement as to what a "well known registered port" means. Your original e-mail mentioned all numbers below 49152.
I was relying what IANA says (ref. www.iana.org/assignments/port- numbers), namely:
- The Well Known Ports are those from 0 through 1023. - The Registered Ports are those from 1024 through 49151
Operating system have various definition for these random port number ranges. Windows XP, for example, would allocate random number in the 4096-65536 range. Your proposed rule would break many applications that use random port numbers for things like instant messaging or VoIP.
I see. This does defeat the proposal as is. Thanks for the info. RD
