I was just following howto and your instructions ;-)

If I really want? Is there any other way than specifying 6to4 relay for
IPv6-in-IPv4 packets? Isn't that needed to communicate to 6bone (3ffe::)?

Okay, now I tried that (local any and local 193.166.92.78). Still ping6
doesn't work. However, tcpdump shows that I get reply BUT ping6 do not get it.
ping6:

What might cause that? Something between eth0 and tunnel?
I have a hole in firewall for IPv6 so that it won't be blocked.
$IPTABLES -I INPUT -j ACCEPT --proto 41

tcpdump doesn't show any replies for traceroute..
