An algorithm and a set of scripts which work in a closed loop on an OpenWRT router that enable resilient and high availability VPN (openvpn) connection for all connected router clients
This article describes a script based algorithm and implementation for creating a kill switch enabled VPN connection that is resilient to VPN disconnections and non responding VPN servers on OpenWRT routers. This will result in high availability VPN connection to all router clients, and will avoid data leaks to regular network during the automatic reconnect attempts.
