Hey Mister A,
Thanks for your reply - but yes I open ports on router for the right ip-address, I do take care to check that of course.
As I said, settings exactly the same as in ubuntu - and all worked fine.
I made several port forwarding rules for several ip-addresses because the address changes sometimes - 1, 2, 3.
However, just found out that when I connect to my router via a lan cable, torrent client says the port is open.
When I switch back to wireless connection (via the same router) it closes again...
Thanks for any help!
