Secure OpenVPN Access to a PLC using 4G Router

Scenario

We have a PLC, data logger, IP camera or other remote device with ethernet or serial ports that we want to be able to remotely access on demand in a secure manner.

In this example we will focus on accessing a PLC with an ethernet port, and we will use a standard dynamic private IP SIM (eg with an APN such as telstra.internet).

Remote Access to PLC or HMI

Cervello Network Manager will allow us to establish a VPN between a PC/server and the remote MTX Router using OpenVPN GUI.
