Someone knows how to disable ARP on OC200 when TL-R605 is adopted?

Could you be more specific? What do you mean by disabling ARP on OC200? Why do you want to disable it?

I just want to disable this feature Enable ARP Spoofing Defense

Beacuse I have got an error message every 5 min that said there is an IP conflict.
I know how to Enable or Disables this feature when the router has not been controlled by the omeda controller, But I cannot Find the disable opciones once is controlled by OC200
Note: only happens after I apply a fixed ip address to differents device.

When there is an IP conflict, I think we need to check the network setup and avoid it, but not to disable the firewall to report the error. May I ask what's your application scenario to make you share a fixed IP address among different devices?

There is no option to disable ARP in Controller mode. It seems that the ARP Inspection feature is supported only in Standalone mode.
