ASUS Router Blocking Access To Virgin News Server. HELP

[lettuce]

I have been having problems with the virgin news servers (news.virginmedia.com) in that i cannot access them using Newsbin or any other program, it gives me the error message that it needs a username and login details to access the server but Virgin doesnt need a login or username to access the server.

Upon fault finding i found that if i disconnect my ASUS RT N56U wireless router and connected my PC straight up to the Virgin Superhub router then i could get access and everything downloadeds fine. So it would appears my ASUS RT N56U router is blocking the virgin news server, any ideas how its doing this and what i need to alter so i can connect to the news servers through the ASUS router?

I did have the DNS section empty with the ASUS router for DNS1 and DNS2 but then have tried adding

194.168.4.100
194.168.8.100

but that doesnt appear to fix the problem

EDIT: Should point out it only appears to the news.virginmedia.com it seems to be blocking as i also use astraweb and that downloads fine
