Create a VPN chain (spoke/chain) based on OpenVPN or Wireguard

If you need access to the internet through the home or corporate internet in the absence of a white address from both sides (server and client), you can purchase (form free) #vps server and on its basis build "Spoke" using #VPN services #wireguard or #openvpn :

Client (NAT / Firewall) --- VPS --- (NAT / Firewall) Server

In this case, both #client and #server (who do not have a fixed public IP) will be connected to the VPS server with a public white IP address on the Internet, but the Client will get access to the Internet through the Server (with the IP address of the server).

The work includes the router (Server) and server (VPS) settings, a configuration file will be generated to install on a PC or other router.
