Thanks Khaled for trying and replying your results to me!
Now I feel very sure that it should be possible, for me too, to make it work!
I was able to forward the ports under Connect->Options->Ports -
then I shall be able to successfully forward the rest.
Maybe rebooting the client or the router ...
Funny was that I found out, after all manual port forwarding,
that the Windows Upnp-service wasn't running on my machine ...
Don't remember that I stopped it.
I'll report any success or failure.
