In the Host details section under the Dynamic DNS tab, IPv4 address can be set to either Use port IP or IPNATed public IP. Below that is the option for IP edit checking interval.

If I understand this correctly, when set to IPNATed public IP, the XG firewall has to contact some server on the internet to determine what the public IP is. Therefore, it makes sense to set an interval at which it will contact this server.

However, when set to Use port IP, the XG firewall should be aware at all times what the port IP address is and should be able to immediately update DDNS if it changes. When set to Use port IP, the IP edit checking interval should therefore be grayed out or disappear.

The way it works now, the interval is used either way. Even if a reboot occurs between one check and the next, it still wait for the end of the interval.

Please add DNSimple as a Dynamic DNS provider. The link below provides info on their Bash Client as well as APIs if you should choose to bake your own or extend some convenience features into the Web Interface. All that is needed to make this work on an XG is some sort of scheduler (LaunchD/Cron) to run the bash script.
