To test the connection, use an address within the VPN network. Normally the address of the OpenVPN server is used here. If you have set a timeout, it should be minimum three times longer than the ping period! If no successful ping is forwarded to the specified address within this time window, the connection is considered interrupted. An attempt is now being made to establish a new connection to the OpenVPN server.
