@Tretoar 

Do you mean there is a VPN server setup on the C7? What kind of VPN server are you using on the C7? Which gateway are you talking about and why do you want to change it?

Please kindly describe the issue in more details, and we will see if there any issue with that, thanks.

Goodnight

Anticipated apologies for the eternal in answering the situation, since this raised has been an eternal problem at work that I can not solve yet.

Let's go in parts, Jack would tell us;)

Remotely I am trying to manage this device to change the gateways through which it goes to www. A rural area that has a few dedicated fiber lines.

This same I connect via anydesk to the network to access and thus change the gateway of the device mentioned above, this is where the problem begins, when physically I am connected by ethernet I can change the gateways without problems but when I enter via anydesk tunnel I do not let me save the changes, I never had this kind of incident that seems suspicious to me. Describing everything discarded would become an infinite thread and first I want to receive a focus on what it does.

I hope I was concise, thank you very much.
