unable to connect from internet/network unreachable

Hello everyone,
I seem to have a bit of a problem with my ipv6 net: Aiccu connects without a hiccup and I get an IPv6 address on my sixxs network and radvd sends out IPv6 network addresses for the other computers to use and they can access the internet.
So far, so good. But when I try to connect from the internet to my server using IPv6 I can't get any further than the last hop before my server (firewall on server accepts ssh, http, ping and a few other things).

$ ssh jf@2001:610:xxx:xxx::1

Does anyone have any idea what I've done wrong?

The !N indicates that the next hop cannot be reached. For SixXS this means that the tunnel that is following that hop is not up.
You might actually want to specify what your local node is (the one with the tunnel) and what the remote side is. Obviously the tunnel at the source of this traceroute works, the other one does not.

I checked last night, IPv6 addresses were assigned, I could connect to them on all interfaces but traffic from outside failed to connect. I had to restart AICCU several times (no error messages) before I could connect from remote.
Maybe it's because of the dist-upgrade I did a few days ago.....

Actual details are quite useful.
Restarting aiccu does not change anything as it does the same thing over and over again, it does not have magic voodoo powers to resolve misconfigurations.
