According to the udp encapsulation draft, 2. Packet Formats 2.1 UDP-encapsulated ESP Header Format .... The UDP header is a standard [RFC 768] header, where - Source Port and Destination Port MUST be the same as used by IKE traffic. But, one of the ports must be 4500 on the wire. And the destination port seen by any implementation must be 4500. There seems to be some implication that encapsulation could happen over port 500. I think the language should be tightened to that this only happens over port 4500 (and an ephemeral port in some cases). I think this could lead to possible interoperability problems otherwise. chris stillson IPSEC crypto monkey x82477 Note: Preceding comments written by an engineer. There is nothing to read into them.
