Click Port Forwarding on the navigation menu to congure Port Forwarding. Port forwarding
allows you to specify a port or range of ports to open for specic devices on the network.
This might be necessary for certain applications to connect through the router. In some
cases you may have two applications running on dierent devices which require the same
public port. Port forwarding also allows you to remap a dierent external port to each device.
