This setting defines the Data Port on which the device is accepting incoming data connections.
For UDP communications, outgoing UDP datagrams are also sent from this port. For TCP communications the device accepts incoming data connections on the data port but establishes outgoing connections from a pool of ephemeral ports in the 10000-10255 range (port number is incremented with each new connection).
