What I read from your very brief post could indicate that another application is using that specific port.
Use ports > 40000
For a more thorough answer please report what connection, OS, modem, router, etc.

If you are indeed using a router, then you will need to forward your listening port, and set a static IP address in windows.
Portforward.com has guides for this.
