No, its a static IP deligated by the Main-Router (where i did open the Ports for WireGuard and VPN) So the Flint gets from the MainRouter a Static-IP and i put this IP here:

The WireGuard-Devices use a selfhost-domain (mainrouter forwarding) in the WG-Configurations to forward the changing IP4 of the mainrouter. This runs pretty stable.

Is this ruining Goodcloud ? because i changed the DHCP to static ?
as i said above, the goodcloud webgui adding the router, but its stays offline in the goodcloud account and in the webgui it will not log in - the cloud staying yellow
