Collect information from remote offices into one?

Question

VPN

Good afternoon!
I'm interested in such a question, there are 5 offices that have office video surveillance in the LAN on the web interface, and a self-written web shell with various tasks for employees. The director wants to see these web resources remotely via the Internet. You can withdraw them only to the central server for these 5 offices. Is it possible to make it so that local resources will shine on the Internet and they will be visible?

We combine our vpn network with routing to clients, ffmpeg, web server with php

Answer 2

You have a network in star configuration. Take any proxy in general (even the notorious haproxy) and route this traffic out. Business for an hour of work with reading documentation

Answer 3

set up tunnels to these offices, set up routing and watch anything. exposing internal services to the Internet will result in the construction of a protection system and its constant monitoring with the development of a set of measures to restore them in case of hacking or unauthorized access with subsequent prevention. what is cheaper for you - consider.
