Fred, Thank you very much for the comments. Questions to you: If a CPE-1 has private IPv6 addresses for its ports behind NAT, and CPE-2 has IPv4 address, can CPE-1 communicate with CPE-2 by the NAT's IPv4 address? Linda -Original Message- From: Fred Baker

Even a NAT64 is not needed. What we do now is we go to a GW (lets call it like this for now) and the GW rewrites the outer header of the tunnel srcIP and dstIP from v4 to v6 or vice versa. It is kind of decap/encap operation on the outer header as if you terminate the tunnel and reinitiate the

The semantics on how to handle this is a different discussion. I believe the basic operation needs to be understood first. After we can see how this should be signaled. On 05/11/2018, 23:23, "Linda Dunbar" wrote: So we need to add another type to the subTLV: Mapping (for the scenario of

I also share bad feelings here ... Do it natively with IPv6, no mappings, nothing strange. It will also make possible for existing hardware, to do offload in the chipsets, which I don't think you're considering. I also feel really weird that you are writing Ipv6 instead of IPv6, no reason for
