That would be a pretty simple, headless solution if you could use it to get what you needed from the systems, especially if you can then connect it via USB or ethernet to the end device and pull the data. Obviously, as with any headless device it might not work 100% of the time so maybe a tablet with vpn client might work if it has the right connectivity. You could probably put the sim from a usb modem into a tablet.
The OpenVPN virtual appliance is fair straight forward to get a basic configuration going and you can have 2 concurrent connections for free, I use it to access my home network while I'm away, but obviously you would have to check the ELA to see if you can use the free part for commercial use.
BurningSky got a reaction from Theguywhobea in AWS instance as a VPN
