I have a Project that I want to be able to view from both inside the plant and through the internet

Now I can add security by assigning roles on wether they access the site locally or via the internet (IP ranges), but I would like to be able to identify devices so that I can give access to only certain devices like what you would do with MAC filtering on a local network.

Edit:

I forgot to mention that I am using perspective
