Right, and a gamer will want to use something that makes gaming easier and more reliable, and not care whether it’s IPv4 NAT or IPv22. Gamers are already quite aware of issues like port forwarding, and various classes of NATs. They might not understand what they are, but they know certain configurations are required. I don’t know which ISPs are using the filtering models that have been presented in the IETF, like RFC6092 and draft-ietf-v6ops-balanced-ipv6-security-01. The snag of course is that addressability and reachability are not the same. I would assume RFC6887 is the IETF approved approach to firewall traversal for IPv6 where the firewall isn’t open. Tim
