Thanks LOTR,
No problem.
I am in Switzerland, so my provider is Bluewin, a part of the incumbant telecom provoder Swisscom.
I did wonder about the UPnP, so I did already the port forwarding.
My modem/router is:
Belkin ADSL Modem with Built-in 802.11g Wireless Router.

I'll try the bug report as u suggest after half an hour or so.

Thanks for the help
