Security is an important aspect of any IoT solution based on the Azure IoT Hub. Sometimes, your IoT solution needs to explicitly give the range of the IP addresses from which the devices can connect as part of the custom IoT security configuration. IP filtering enables customers to configure IoT Hub to only accept connections from specific IP addresses assigned to the IoT devices or to block communication for a specific range of IP addresses.
IP filtering with IoT Hub
Getting ready
The IP filter configuration is very easy for an administrator. These rules apply any time a device or a backend application connects on any supported protocols (currently AMQP, MQTT, AMQP/WS, MQTT/WS, HTTP/1).
The IP filter allows a maximum 10 rules...
