- From now only a single OpenVPN connection is written to the OpenVPN configuration file - If multiple connections are matched given the user parameters (i.e. city, region), it is picked at pseudo random using the current time as the pseudo random seed. - Not relying on Openvpn picking a random remote address, may refer to #229 - Program is aware of which connection is to be used, in order to use its matching CN for port forwarding TLS verification with PIA v4 servers, see #236 - Simplified firewall mechanisms
