Hej Erich, Bob, Charles and others, first thank you for your replies. After reading it all, the scenario from Charles seems to be the most detailed while on the other hand I don't see the main advantage. By the way: Yes, there is a sshd running. Also, I was not mentioning this: I already have vpn-connection from my laptop to the leaf box. Is it possible to push the magic paket through the tunnel? That would make all other thoughts unnecessary. Sorry, I forgot to include that in my first question. Well, I found a tool for sending magic packets by directed broadcasts. That should work through the vpn (= over different subnets). There seem to be a difference between directed broadcasts and limited broadcasts. Directed broadcasts are routable. So far. I will try to find out if the leaf box is able to transmit directed broadcasts - tomorrow!
