Thanks, we can rename it with 00 and WG name.

Yes, your understanding is right. NAT44 and 6-over-4 tunnel can be splitted. They
are separate technologies.

In our proposal, we suggest to integrate NAT44 and 6-over-4 tunnel into a same
device box (CGN) so that ISPs can deploy it with a clear IPv6 migration strategy.
Here, we may extend the concept of CGN a little bit. When we talk about CGN, we are
actually referring to a carrier-grade device, which integrates NAT functions and
other integrated technologies.

Best regards,

Sheng
