Change or disable the lan gateway

is it possible to change or disable the LAN gateway via genieacs?
we are monitoring mercusys routers (tplink) via genieacs.
Thank you

Why do you want to disable the LAN gateway?

we are doing some tests to temporarily block LAN network navigation, while still maintaining the router’s remote reachability.

Is this for non-pay disconnect of customers? A better way of accomplishing this two interfaces on the router. One for customer traffic, one for remote management. This way you can disable the internet, and still reach the router.

At any rate, there is no way I’m aware of to just disable the LAN gateway. But you can disable the interface. For TR181, it would be Device.Ethernet.Interface.{id}.Enable where {id} corresponds to the instance ID. For TR069, it would be InternetGatewayDevice.LANDevice.1.LANEthernetInterfaceConfig.{id}.Enable

If the goal is to disable all customer traffic, you would need to repeat the same procedure for the wifi interfaces.
