NO IPv6 traffic

Hi! This is T8358 Since yesterday's reboot of the gateway I don't get any IPv6 package over the tunnel. I'm slowly getting out of ideas on what could be wrong and how to debug this.

As there is no problem with the SixXS side of this problem, please peruse the forums for resolving the problem, we do not have the time play helpdesk unfortunately. There you will need to provide quite a more details, see the contact page for the list, firewall might be a good thing to start amongst others, and likely next to check the Tunnel Live details in the webinterface and to wireshark/tcpdump the traffic.
