Add Ethernet and Wi-Fi gateway requirements to your allowlist

Learn which hostnames, TCP ports, and NTP domains to allow so Ethernet and Wi-Fi gateways can connect and sync sensor data accurately.

What you'll need

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

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

Gateways require open communication on TCP ports 8883 and 443.

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:

Domain	URL
`.pool.ntp.org`	`0.openwrt.pool.ntp.org` `1.openwrt.pool.ntp.org` `2.openwrt.pool.ntp.org` `3.openwrt.pool.ntp.org`
