Ubuntu Upgrade over IPv6

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.

policyd-weight IN_IPv6_RBL=4.25

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.

IPv6 Tunnel Broker

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.
