"I wanted to understand how to find the RFC details (Hostname details) in the Winshuttle Integration Servers which tell me how Winshuttle is connecting to SAP.
Basically if we can get the Hostname we will be able to get the port number details which is what this exercise is ultimately for..
33XX and 48xx
Used for the RFC call to the SAP GUI
We want to know the XX values in the RFC call to SAP.
You can use Tcode ST05 to check what RFC calls are made; but for the hostname details you would need to work with the respective IT team.
Please see below article regarding what Ports are normally used.
