To be very honest, situations like Tore’s have always made me question the wisdom of a special prefix for IPv4/IPv6 NAT. One is communicating with a peer at an IPv6 address. One got the address because the initiating SYN-or-whatever came from it, or the address was provided in DNS. Tomorrow, with any luck, it will be a native address; today, it is a /96 embedded in a /64, one of many /64s in the network. Why should I know or care that the path to the peer has a NAT in it? Yes, there are some end to end session assumptions that fail. No matter what I do, they will fail. I at least have as good connectivity as I would have in an IPv4 network.
