Motorola MT7711 User Manual page 34

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.
