Can you provide a screenshot?

[HeatHunter]

so the server is in the same network as you are?

Is it running on the same machine, or do you host it on a dedicated machine?

 

What are the IP-Adesses and subnetmasks of both (client and host) (if the server is a dedicated pc).

 

Is the server running on the internet? (did you buy a dedicated server from a hoster?)

This probably belongs in the Tracker, but please at least provide the requested information, and whatever else you can find.  Your simple description of the problem is not enough to work with.
