Hi,
RMS VPN Hubs are not intended to be used in the way you described. The purpose of the RMS VPN hub is to create a secure tunnel to your Teltonika device. Once the tunnel is established, you should be able to access your LAN devices through the VPN tunnel using your TRB140. Is there a problem with this method? Can you please explain what you are trying to accomplish?
Kind Regards,
Andzej
