Hi

Hmm... this is strange, port 999 is used for time syncronization 5678 is
used for the syncronization of data and finally 5679 is for sending out a
heartbeat signal.

to be honest i only thought thise ports was open if ethernet sync was
enabled? maybe it used as a part of the passthough internet conenction?
