I got a Warning on DDNS test

When you run the DDNS test on Dynamic DNS page, you may get the below result.

It is not a Warning message or an Error message. It is a reminder to you.

It is a test result about your router position. If your GLiNet router is sitting as a secondary router in your home network, this message will appear.

This message will not disappear even if you have done the port forward on your primary router.

It is just keeping to remind you the router position is behind NAT. If you need any service to pass through the NAT, you need some extra settings.

If you get the below message, then you may using a cellular network and DDNS setup is not possible.
