If multiple connections from the same source to the same destination are used then the NAT64 needs to use a separate port. But using the same port in the cases where the destination is different would be a massive saving on ports, and therefore on expensive IPv4 addresses. > From my point of view this will break connections. If it was implemented as you show then it would indeed break. Cheers, Sander
