Make sure that the Port Forwarding radio button is selected.

Select the protocol type of the ports you are forwarding from the Protocol box.

If you are forwarding a range of ports separated by a hyphen then enter the lowest number of that range into the Base HostPort, Global PortStart box and the highest number of that range into the Global PortEnd box. If you are only forwarding a single port number then enter that number into both the Base HostPort, Global PortStart and the Global PortEnd boxes.
