Hello!

I have a problem i need some help with.

The situation is i have a device that i program with an UI software.
Once programmed it is shipped to panel builders that incorporate the device into a panel.
The panel is then connected to a 4G router.

My device is connected to the router with a LOCAL address. The 4G router has a static IP which connects to the clients process network. Data stored on my device is reached through the public IP of the router of course.

Now the client wants to change passwords on a regular basis on my device for security reasons which is fine.
I need to reach my device with an UI software.
Now to be able to reach my device the administrative computer needs to be on the same network as the device itself (The LAN)
which means i need to connect directly to the device. I cannot use the public IP of the 4G router for this task.

So the question is can i set up a VPN like connection locally on the administrative computer like setting up a network adapter that the UI Software could connect to "tricking" it that it is connected directly to my device. The adapter the UI would use could be connected to the network adapter used to connect to the process network.

To add some more problems.
I cannot use my computer on the process network. I could only use a virtual machine for this. Located inside the process network.
