You can run "aiccu test" and it might show you where the problem is.

Can you show the output of:

ip -6 addr

and:

ip -6 ro

?

Can you ping it?

cl-1048.lon-02.gb.sixxs.net is your end of the tunnel; its IP ends
in ::2. The sixxs POP's end will be gw-1048.lon-02.gb.sixxs.net and
its IP will end in ::1. If you can ping that then the tunnel works
to the POP at least.

Cheers,
Andy
