I would like to connect my computer (where my hard drive is with a program that I need) to my laptop. I would like to have my laptop call the program for what I have in my computer. I wanted to ask if I could combine two devices with one VPN. I also think I can't do it through the router but I can be wrong too. I want to have access to this program from another point, for example from home, which is with my aunt.
The easiest thing would be to implement the VPN using a router.
The Fritz boxes can do that relatively well. You set them up at home and then you can access them from afar using Shrewsoft (software client).
You can't start the program on your laptop.
