I want to add the IoT Hub and Azure Container Registry in the Destination of Outbound port rule of a azure VM where IoT Edge runtime is installed, so that IoT Edge can send data only to specific IoT Hub. I tried by adding the hostname of the IoT Hub but it is not helping. Providing Any in the destination is working but I want the port to be accessible only to IoT Hub.259934-screenshot-145.png

Please let me know if there is a way to achieve this.

    @Satyam Chauhan
    I think you can use the service tags ,AzureIoTHub is servcie tag .
    Below is the list of service tags with ip ranges.

    To add a service tag you may need to use azure cli as i believe the azure portal do not support adding service tags.

    az network nsg rule create --resource-group myResourceGroup --nsg-name myNSG --name RDP-rule --priority 300 \
    --destination-address-prefixes '*' --destination-port-ranges "AzureIoTHub " --protocol Tcp --description "Allow RDP"
