Which ports do I have to open in my firewall?

The air-Q communicates with the Internet via port 8883, which is often used for the MQTT protocol, with the MQTT endpoint alguhxninl5b7-ats.iot.eu-central-1.amazonaws.com.

The air-Q uses pool.ntp.org as its time server.

For the air-Q to function properly and send data to the air-Q Cloud, these addresses and ports must be enabled by the firewall.
