HERE IS HOW TO TURN PORT FORWARDING ON:
Type the router's address in an Internet browser's address bar. (By default the router's address is 192.168.0.1). The Setup Wizard appears.

Under Advanced, click Port Forwarding on the left menu bar.

From the Service & Game (or Service Name) pull down, select the service that you will host. The services the router knows about are listed here. If the service does not appear in the drop down, add a service as described in the next section, then return to this step.
Enter the IP address of your local server in the Server IP Address box.
Click Add.
Click Logout to exit from router settings.
