I tried the port scan but it's all new stuff to me, I dunno the range of ports.

Tried changing ports in LW to the ports reccomended on the forum i.e 4443 and 5190 and 5566 but got no joy.

Do I have to change both listening port and Manual Port Forward ? because i've tried both that and just leaving the Use UPnP but nothing has worked.

Is this definatley an ISP issue as I've used Tiscali for years with several different file sharers and never had this problem until a couple of days ago?

It's a bummer
