Review your game or device documentation to find the port or ports that need to
be forwarded. Also, determine the IP Address that your device is using. You game
or device documentation should show you where to find this.
Your game or device may need more than one port to be forwarded. In some
cases, the ports will be numbered sequentially, in a range. In other cases, the
ports may be separated. In this case, you will have to set up a separate
forwarding rule for each port.
