Prerequisites

Before setting up your AirPort devices on your computer that runs AirPort utility, make sure that you have set up the below:

  • Purchase your own domain name and register it for DDNS service or register a free third-level hostname here.
  • Sign up for membership to obtain the Shared Secret (TSIG key) in the MD5 format from the API Credentials section of the control panel.

Configuration
