Yes, I double checked the routes. I checked the neighbour discovery
with wireshark, it just didn't respond. Once the router was in the
host's neighbour cache (showed up in "ip -6 neigh show because of a
ping or something else from the router to the host) communication did
work fine.
I'm not sure how teredo would help with this, it is purely a local
problem. My 6to4 seems to work fine.

Hmm, still no luck. Maybe I should look into teredo just to try this
one. But ipv6.google.com works... is there a list of ipv6 sites that
I could test more against somewhere? What would be really useful is a
search engine that only crawled ivp6 sites...
