Recently I managed to configure a tunnel and route the /64 subnet provided on a small atom computer running Ubuntu server 12.04 through the FAQs and the Wiki (thank you all very much for the time and interest you take). That small box is connected to a switch, that is itself connected to a Mikrotic Routerboard that has wifi capabilities and in this way, provides IPV6 conectivity to all the gadgets, portable computers, phones, etc, that are in the house. That switch also has a cable to a powerline adaptor (TL-PA210) that, through the electricity cables, expands the LAN to a a couple of ubuntu 12.04 desktop computers, each with one powerline unit. The thing is that whatever goes on wifi works OK, but the desktop computers don't. And after many tries and tests I have concluded (it works ok if I just plug a wifi-less portable computer running lubuntu 12.04 in the switch) that it is the powerline units that don't carry IPV6. I believe the German gentleman on the following link is also complaining about a IPV6 conectivity problem with the same units. http://www.heise.de/ct/hotline/Powerline-mit-IPv6-1613463.html Do you think I could be right in my conclusion? I thought powerline worked at a different level and it wouldn't matter whether it was carrying IPV4 or IPV6.
