How do you expect anyone to help when you don't provide any information about the server in question? Is it a windows server (bleh), a linux-based one, a regular windows computer in your basement you call your "server"?
You also shouldn't be using a port forward tool, as I would assume it only works for your local machine. Unless your using remote desktop to run it on a windows server, in which case you still shouldn't be using it because UPNP probably isn't supported for opening ports by your host. Basically: don't use that tool.
Look through the control panel provided by your hosting company and check if it mentions anything about a firewall, and open the port there. If that doesn't work, you'll need to open the ports you want through the firewall on the actual server.
Also, you might consider actually searching the forum for topics like this; a lot of them exist (and ask better questions than "help, this tool won't work on an environment I didn't specify").
