Hi Leo,
Since you can reach your default gateway, but not "the outside world",
the next step would be to try to see how far you can get. Use
traceroute6 to see how for you get. Try a couple of different
destinations and see if that makes a difference.
Also, provide your routing table (the output of `netstat -rnf inet6`)
so we can see if there are any problems there.
Cheers,
Paul 'WEiRD' de Weerd
