Hi, I have a ongoing project to deploy containerized control systems to remote site.
Each container consists PLC, Ignition Edge and multiple other TCP/IP devices under local subnet.
I would like to install a 4g modem in each container, to allow the container to connect to a central VPN server, so all containers are within the VPN network.
Can anyone shine some light on how it can be achieved?
My initial thought is to purchase 4g modem with vpn server/client function, so I can define DDNS and OpenVPN to connect each container to the cloud VPN before dispatching to site.
I found the ASUS 4G-AC68U has the requirement function, but it’s very difficult to find it on the market.
All ignition edge devices are talking to the cloud via MQTT at the moment, it does not require VPN setup. But I would like to install ptz camera as well, once installed, the video files are too large to send to the cloud, they have to stay in local HDD, once under the same VPn, the ignition client should be able to view the files easily.
