[j-nsp] M7i as LNS

[Matthias Gelbhardt]

Hi!

At the moment I am trying to get a M7i as LNS working to terminate DSL  
lines. At the moment it seems, that the tunnel is trying to build, but  
could not be established, due to a dead tunnel 6 pic. I understand,  
that I have one of these, but do I have to switch it alive somehow?

the logs:
