Adding network requirements to allowlist is only required for Ethernet and Wi-Fi gateways, not cellular gateways.

Hostnames

Gateways require the following hostnames to be added to your allowlist:

  • us-east-prod-mydev-hub.azure-devices.net

  • eu-west-prod-mydev-hub.azure-devices.net

  • au-east-prod-mydev-hub.azure-devices.net

  • jp-east-prod-mydev-hub.azure-devices.net

  • in-south-prod-mydev-hub.azure-devices.net

  • prod-dps.azure-devices-provisioning.net

  • global.azure-devices-provisioning.net

TCP ports

Gateways require open communication on TCP ports 8883 and 443.

NTP connections

Gateways make NTP connections to synchronize their clocks so that sensor readings are uploaded in the correct order.

Please ensure traffic to the following domain and URLs are allowed:
