@akcoder SpService is different, of course, I pasted the wrong line… We use both trustdomain and sptrustdomain and they work fine on TR-098. Unless there is already a path, nothing is editable in TR-181.

@martink, we “solved” it by switching to TR-098 with this:  
declare(“Device.ManagementServer.X\_ZYXEL\_DataModelSpec”,null,{value:“TR-098”});  
This will reboot the device and re-read it, but it will be left unchanged.  
After that you can do:  
declare(“InternetGatewayDevice.X\_ZYXEL\_EXT.RemoteManagement.TrustDomain.[Enable:true,IPAddress:10.0.0.0,SubnetMask:24]”, {path: now}, { path: 1 });
