I have a physical device which is attempting to connect to IoT Hub using MQTTS protocol (port 8883). I am working within a corporate network environment, so I cannot have port 8883 left open. IT department is asking for source and destination IP addresses to allow a connection from the device to IoT Hub. I am able to set a static IP address for the device I am setting up, but I am unsure if I have given IT the proper information for my IoT Hub. I thought that according to Microsoft documentation
the destination should be set in the format myhub.azure-devices.net. I relayed this information to IT, and they claim to have done this, but I still have not had any luck with connecting the device to my IoT Hub. Is there something I am missing here? Does the port have to be left completely open? Any thoughts or advice is greatly appreciated.
