Okay, I know I might become annoying for you, but now something very strange happened. While I was reading myself through the port forwarding and router stuff once again, my FW ( I know that's here the LW forum, but I've got the problem with both) suddenly got a 'excellent connection' without me doing anything, no change on config. or system. I therefore post here now the 'bug report' while the client is running.

From FW

Since I suspect the bug (it seems not to be the ISP who blocks the client) to appear again, there might be some clever geek here who can figure out the issue.

I've just shut down FW and tried LW in the hope that it also would connect. Unfortunately, it doesn't. Then going back to FW I got an instant (2-3 sec.) connection stating 'excellent connection'............for now I have to assume that the bug is with LW.
Anyone interested in fixing it? Maybe LOTHR??
