I'm thinking of a kind of a relay-proxy for that. I don't get a connection. I called the hotline. Tomorrow I will call again and speak to his boss, I think. Connections don't last longer than a few minutes.
Some people say, that emails also got lost.
The new network layer behaves quite well. But nevertheless there is much to do. The link for dev10 is dead. This might be due to the problems I had with my ISP, but I don't know for sure. I don't have the jar file for dev10 anymore, so I can't even upload it again, sorry for that guys.
