Industrial Internet of Thing (IIoT) is growing the desires and requirements to communicate with remote applications among machine to machine (M2M) devices for the purposes of controlling or monitoring of either the machine itself or its environment. The challenges and practical needs are in terms of security, operability and scalability. This is where VPN (Virtual Private Network) plays a crucial role for reliable data and centralized data administration. PROSCEND M300/M301 Industrial 4G LTE Cellular Routers provide a highly secure and rapidly deployable VPN solution designed specifically for industrial-grade machine to machine (M2M) applications.

With support for Internet Protocol Security (IPsec) and OpenVPNPROSCEND M300/M301 Industrial 4G LTE Cellular Routers achieve secure interactive tunneling access to devices. It can be configured VPN tunnels with other PROSCEND Series Routers or third party VPN routers and provides three main types of VPN scenarios for M2M connectivity.

  • Site to Site VPN Connection
  • Hub-and-Spoke VPN Topology
  • Remote Access VPN Application 

In a Site to Site VPN ConnectionPROSCEND M300/M301 Industrial 4G LTE Cellular Routers offer encrypted data from one VPN gateway to the other, supporting a secure link between two sites over a third party insecure network like the Internet. 

Site to Site VPN

In a Hub-and-Spoke VPN Topology, multiple VPN routers (spokes) communicate securely with a central hub. PROSCEND M300/M301 Industrial 4G LTE Cellular Routers act as a gateway extends between the hub and each individual spoke for flexible extension and easy deployment. The following illustration shows a PROSCEND’s Cellular Router via IPSec VPN configuration that connects an enterprise’s main office with branch offices using persistent connections to a third-party network or the Internet.

In a remote access VPN Application, all connections between the end devices and the gateways are encrypted with VPN tunnels. PROSCEND M300/M301 Industrial 4G LTE Cellular Routers enable the users to access their data and control the devices from the central site to the remote sites wherever they may be, providing secure and reliable connection. The following VPN solutions specifically for industrial automation industry shows PROSCEND’s Cellular Routers connect to the central office via VPN for communicating with the distance IP-based devices or Modbus devices to monitor data securely and control the emergency immediately when the working status has any warning.
