Hi all

we have developed a RFC server based on JAva Connector. The connection between SAP R/3 and the RFC Server is secured by a firewall. Which ports need to be opened?

My assumption was that the gateway port 33xx (in our case 3300) is enough but the connection does not work and in net stat I could see request from other ports???

Thanks you any help

Michael
