We are making a "test" enviroement (thru AWS cloud instance) and had a SAP B1, SQL server and B1if installed in the same AWS cloud m/c.
Most of the inbound ports are either well controlled or default closed from the AWS cloud m/c firewall. However, our IT service provider just told us to open 2 additional ports (1433 and 2099), in order to get intercompany working. Humm .. does it make sense ?? Since we have all components in one test server (=AWS cloud m/c) and how come we need 2 additonal ports opened to the world in order to get intercompany traffic flowing internally.
