The Raspian and Lubuntu releases at http://www.lemaker.org/ are yet not supporting Tokenized Interface Identifiers.
I fixed a minor problem with the UFW in my Lubuntu installation a few minutes ago.
Even if there are already IPv6-enabled mirrors, that help to maintain an IPv6-only Ubuntu installation, it’s a little tricky to apply a release upgrade.
Watch out for any
IN_IPv6_RBL scores in your policyd-weight logs.
If you see regular hits, you probably have to either upgrade your policyd-weight or disable rbl.ipv6world.net manually.
It’s fairly easy to set up an IPv6 tunnel on any (W)LAN-connected notebook 2 hops away from the DSL uplink, see http://tunnelbroker.net for details.
But this will also bypass the router’s firewall leading to public access to the tunnel endpoint and further.
