Iam currently stuck getting debian server to work with my client (Ubuntu). The tunnel is working succefully from the server but i cant get it to work for my client. 

From my client i can ping to the server but not to the ipv6 endpoint.
I also enabled port forwarding so it is allowed.

This is my client ips: (For some reason i get two global IP:s)

I tried several combinations and probably been working with this for over 20 hours now  :o
