Well it would seem that the two issues are related. I'm currently accessing my ftp account for my ntl webspace. I do something (not quite narrowed it down yet) which cause an incoming TCP response on various ports in the 22XX range. The firewall then promptly blocks upload.ntlworld.com (winnersh data centre) and then the ftp appears to me to be broke, but actually its just my firewall blocking it.
I've just applied a rule letting it through so hopefully that should solve the problem. Thanks for your interest anyways Stuart
