Both are running Debian unstable. On the portable computer
network-manager-gnome is managing the network connection.

The only difference I can think of between the working and non-working
client is, that I had the NoMachine Client installed before on the
*working* client.

Works. (ssh -XC 192.168.x.x)

Did not work.

Sorry, I do not have another server. So I cannot test that.

I will do that, if the information below are not helpful.
