Router blocks newgroups ( newsleecher )

Hi there since yesterday i bought a new Router Tp-link TL-WR1043ND
with the following firmware: 3.13.10 Build 120210 Rel.62735n


But when i start Newsleecher or a similiair program, it won't connect to the newsserver ( XSnews ) but with my old router i don;t have any problems at all.

I tried to open port 119, turn of the firewall, nothing worked.

Could somebody help me?

Zinder.
