Thanks for the suggestion. It is not planned to change the CTM mechanism. It is designed in a way that when using the rsp.mbCONNECT24 server, it is not used as a "stand-alone router". A kind of hybrid of two things but still use all functionalities like the CTM is a special case and therefore not on our roadmap for now, but also not eliminated.
But when reading the application, it sounds like a "VPN port" application. The component that needs to read out the data can be connected to the VPN port and has permanent access to the LAN-components of the routers. For remote access to that component connected to the VPN port you can use a mbNET router + web2go (VNC or RDP).
Thats just an idea from other, similar applications.
