Incoming LAN connection

Hello there,

We have hunreds of devices globally and with one customer there was a period that we were only allowed to connect with IP and we configured players that they only accept exclusively Incoming LAN connections.

Now everything has changed. We can't get any remote access via IP address, so there is no way to get remote access to these ~30 devices.

So my question will be, is there way to change this Incoming LAN connections setting to DEACTIVATED via cmd. I tried to change General_DirectLAN and LanOnly register keys to 0 and  even try to delete these keys, but it's not working. I still can't connect with TV-ID.

Thank you and BR - Tuomo
