TCP/IP ports required between SAP R3 and SAP PI 7.5 in Firewall

Hi Experts,

We need to establish a communication between SAP R3(EHP 8) and PI 7.5(AEX) through firewall. My client and Infra team needs accurate ports count which are required between this two application to & fro.

I have provided few documents where ports are listed but there concern is they are in series.

Kindly find the screenshot which i have sent them.

Please suggest the list of accurate ports required for communication between

1) R3 to PI

2) PI to R3

UAT testing is on hold due to above issue.
