How to set up vpn to set up cameras on remote networks?

Question

VPN

The essence of my task: you need to configure ip cameras that are located at different locations without leaving home. At these locations there will be my person (installer) who has physical access to the network but minimal knowledge. To configure them, I need to refer to their local address. Is it possible to create a vpn device (such as a raspberry pi or a router with vpn) that can be connected to various remote networks and access local remote addresses through vpn? You need the simplest solution so that you can set it up and use it without problems. I also ask for an explanation of each step so that such a slow-witted person like me can understand)

Answer 1

A simple option is a team weaver.
Complicated -
Raise your vpn server.
Take the second piece of hardware on which the vpn client
connects the client at the facility, to the network to the cameras
(Either with manual settings or via dhcp), depends on the network at the facility.
Next, we check that the client has Internet, after that the client connects to your server.
Next, we look at the subnet on the client (which he received at the facility) and register the route to the remote subnet (where the cameras are) on your VPN server so that your PC knows that you need to go to the camera subnet through the VPN server
Your PC must also be connected to vpn server...
Something like this
On Mikrotik, it rises in 10-15 minutes...

Answer 2

Need the simplest solution

A laptop with TeamViewer or AmmyyAdmin installed (or two or three more similar programs). And you don’t need to explain anything, you connect to a laptop and work as if you are sitting at that laptop.

so that a dumb person like me can understand

All other options are more difficult, require delving into.

Answer 3

For me, the easiest solution to set up is:
- take two microtics (one can be the cheapest 10Mbit / s is enough for you)
- a home microtic should have a White IP
- raise L2TP + EOIP between them, mikrotik from the office should raise VPN home
- at home mic to bridge eoip with one of the ports (not necessary with all)
Accordingly, when all this will rise, then your PC will receive IP from the office network and all the rules for accessing the Internet and internal routing of the office will apply to it. How would you be inside the office.
This solution is not recommended for production - but it is good for tests and temporary work.
