Which ports do Dell DUPs use?

Hi. We're deploying a Dell rack server in a remote location and need to present the host network group with the ports we need open for OMSA, updates, etc.

Does anyone know which ports Dell DUPs need open in order to run firmware and driver updates? I have the Port Information Guide for OMSA/iDRAC but can't find anything about DUPs that are run from the OS.

Thanks.
