Micrologix 1400 TCP and/or UDP Ports Used

What ports, UDP and TCP, does the Allen-Bradley Micrologix 1400 driver use to communicate to a Micrologix 1400? I need to configure a router to allow traffic from the PLC to the Ignition Gateway.

TCP port 44818, nothing else needed, driver doesn’t allow port configuration.

Thank you! I will program the router accordingly.
