Port Information for SAP ABAP server

Hi Expert,

I need your advise on what is the port requirement for connecting to the SAP ABAP server.

I am trying to connect from my machine by GUI to a ABAP server. I have requested my network team to open the below  firewall ports

3200  TCP  for dispatcher

3300  TCP  for Gateway

3600 TCP for Msg Server

I have requested them to open bidirectional. My concern is the network team saying what is the requirment of bidirectional can't it be done with unidirectional.

Please share your comment or sap standard document which says bidirectional ports are required for SAP application to communicate with frontend.

Warm Regards,

Saurabh Gautam
