SAP port configuration
On each SAP server that you will connect to with Direct Link, you need to open the following TCP/IP ports for inbound and outbound communication:
| Port name | Port number | Comment |
|---|---|---|
| Dispatcher | 32<NN> | Used by SAP GUI |
| Gateway | 33<NN> | Used for RFC communication |
| Message Server | 36<NN> | |
|
Note <NN> is the instance number of your SAP system. So, if the SAP system number is 10, then ports 3210, 3310 and 3610 need to be open. |
