Nice, but why do you absolutely require Teredo even for boxes with native IPv6? Of course there's the advantage of direct client2client communication (less latency for clients and less traffic on Teredo relays), but the box should at least fall back to native IPv6 if Teredo is not available (quite odd to talk about native IPv6 being a fallback to Teredo, but anyway). There's at least one CPE manufacturer (quite prevalent in Europe or at least in Germany) that filters out Teredo if native IPv6 is available by default. They added an option to disable this filter, but that's not a good thing. See http://service.avm.de/support/en/skb/FRITZ-Box-7390-int/1439:Cannot-play-online-games-with-Xbox-One In the current state, the XBox One is doing more harm to IPv6 than good. People encounter problems after having IPv6 activated (there are forum posts which told people to disable IPv6 to fix this issue) and Network operators will see less increase in IPv6 traffic (which lowers the incentive to improve IPv6 support).
