How to build a VPN server?

Question

VPN

Hello Dear Connoisseurs!
Recently got a job in a network of pharmacies.
Each pharmacy (and there are 25 of them) has its own 1c database, and they are not synchronized.
I would like to create a VPN server with a small amount, so that it can pull 25 simultaneous connections for video surveillance and have enough traffic for remote administration.
A 1C server has already been prepared on the server.
It remains to stir up the vipienka.
I would be very grateful if you share your experience and tell me how.
PS. The Linuxoid of me is frail.

Answer 1

The lion's share of your resources is video surveillance. For example, 25 points, 4 2MP cameras each is an average of 500 Mbps of traffic. Servers for encryption of this volume start from 500 thousand rubles.

Answer 2

I won't be verbose. As I understand it, Linux does not suit you very much? Sorry, okay. Here is an option for Windows, read and do . It works perfectly, I recently set it up according to this instruction.

Answer 3

1. Budget?
2. Speeds at branches?
Video surveillance will take most of the tyrnet bandwidth, so the faster the speed, the better. Keep in mind that the cost of connection for eurekas can be a very unpleasant surprise.
