No, I'm afraid I've still got the same issues. Funnily enough my problems started around October time too. I have added port forwarding rules to my router, but it has made no difference.

I'm suspecting it is TalkTalk who are blocking the traffic (and I'm sure I've read on another forum that they block p2p traffic for all their users), but have not tackled them over it yet.

I think it may be time to switch broadband ISP. Does anyone have any recommendations?
