I have installed and setup the Flash Builder Plugin for NGS. I was able to connect to the Demo SAP Gateway System and consume the services present in it. Now I want to connect to the SAP Gateway System in my organisation landscape so that I can consume the OData services present in our System. I need some inputs here, in the FB plugin for a flex mobile project, I have to provide a data connect source which will point to the SAP Gateway system. I need to know the port no to which I should connect inorder to be able to access the SAP gateway services via the FB Plugin. In the Demo SAP Gateway system, the port no is 80, do I have to expose the port 80 of the NGS present in our landscape?
