--deleted as it works now, thank you very much--

Ping6 works fine but haven't found anyone who can reach it.
Naturally i haven't the slightest idea what could be wrong.

Does not work from my ipv6 enabled phone.  Check your firewall

Router firewall  may be the reason, but i need some help checking these:

Try purging your firewall rules temporarily and see if you become reachable (i.e. no rules and default policy ACCEPT).  If you do become reachable, then it's your firewall.

Router firewall  may be the reason, but i need some help checking these:

#ip6tables -L

The output from that command is not as helpful as it should have been. Look at the output of ip6tables-save instead.

[dsuha]

Just noticed that rule i had made for port 80 was not there in FORWARD where it should've been.

Now http://ipv6-test.com/validate.php says Congratulations, this website is IPv6 ready !

Edit: Woohoo i can see it working through URL.ipv4.sixxs.org !   Finally.

Seems it needs an ICMP traceroute to be reached. How to make firewall rule for UDP traceroute? Most of the online ipv6 traceroutes seem to use UDP (or something else than ICMP).
Here's one: http://www.4or6.com/traceroute?l=en
