Maoke, Thanks for this question. This subject being new, I take it on a new thread.

The point is that if a NAT64 is upgraded to support 4rd-u tunnels (thus becoming a NAT64+) it can take IPv6 payloads as valid IPv4 payloads. Any protocol that this NAT64 supports is then supported e2e for 4rd-u CEs These CEs need not being dependent on which NAT64 supports which protocols. Note that the NAT64 doesn't need to have CNP code. It just happens that host IPv6 addresses it sees are checksum neutral. (Thus, IPv6 and IPv4 payloads are the same for all protocols that have ports at the same place as TCP/UDP/..., and the same checksum algorithm) RD _______________________________________________ Softwires mailing list [email protected] https://www.ietf.org/mailman/listinfo/softwires
