hi,

Writable parameters arent changeable from acs server because those attributes are defined and enforced by the firmware of the CPE, u can make virtual parameter for ip wan and change in return { writable: false,value: [inform\_message, “xsd:string”]};

Hi,

something like this ?

i created virtual parameters with name “VirtualWANIP”

```auto
“let realParam = declare(“InternetGatewayDevice.WANDevice.1.WANConnectionDevice.2.WANIPConnection.1.ExternalIPAddress”, {value: 1});

return {value: [realParam.value[0], “xsd:string”],writable: false};”

```

Thank You

Hi

That’s should be correct script , after this modify device page and add your created virtual parameter.

“let realParam = declare(“InternetGatewayDevice.WANDevice.1.WANConnectionDevice.2.WANIPConnection.1.ExternalIPAddress”,{value: Date.now() });

return {value: [realParam.value[0], “xsd:string”],writable: false};”
