 * Class Config
 *
 * @property string    $modeSet             OpenVPN major mode: p2p, server
 * @property string    $local               Local host name or IP address
 * @property string    $remote              Remote host name or IP address
 * @property bool|null $remoteRandom        When multiple --remote address/ports are specified, initially randomize the order of the list
 * @property string    $proto               Protocol for communicating with remote host: tcp, udp, tcp-client
 * @property integer   $connectRetry        For --proto tcp-client, take n as the number of seconds to wait between connection retries (default=5)
 * @property string    $httpProxy           Connect to remote host through an HTTP proxy
 * @property bool|null $httpProxyRetry      Retry indefinitely on HTTP proxy errors. If an HTTP proxy error occurs, simulate a SIGUSR1 reset.
 * @property integer   $httpProxyTimeout    Set proxy timeout to n seconds, default=5.
 * @property string    $httpProxyOption     Set extended HTTP proxy options
 * @property string    $socksProxy          Connect to remote host through a Socks5 proxy
 * @property bool|null $socksProxyRetry     Retry indefinitely on Socks proxy errors. If a Socks proxy error occurs, simulate a SIGUSR1 reset.
 * @property string    $resolvRetry         If hostname resolve fails for --remote, retry resolve for n seconds before failing
 * @property bool|null $float               Allow remote peer to change its IP address and/or port number, such as due to DHCP
 * @property string    $ipchange            Execute shell command, format: cmd ip_address port_number
 * @property integer   $port                TCP/UDP port number for both local and remote: 1194
 * @property integer   $lport               TCP/UDP port number for local
 * @property integer   $rport               TCP/UDP port number for remote
 * @property bool|null $nobind              Do not bind to local address and port
 * @property string    $dev                 TUN/TAP virtual network device: tunX, tapX, null
 * @property string    $devType             Which device type are we using? device-type should be tun or tap
 * @property bool|null $tunIpv6             Build a tun link capable of forwarding IPv6 traffic
 * @property string    $devNode             Explicitly set the device node rather than using /dev/net/tun, /dev/tun, /dev/tap, etc.
 * @property string    $ifconfig            Set TUN/TAP adapter IP address of the local VPN endpoint.
 * @property bool|null $ifconfigNoexec      Don’t actually execute ifconfig/netsh commands, instead pass –ifconfig parameters to scripts using environmental variables.
 * @property bool|null $ifconfigNowarn      Don’t output an options consistency check warning
 * @property string    $ifconfigPool        Set aside a pool of subnets to be dynamically allocated to connecting clients, similar to a DHCP server.
 * @property string    $ifconfigPoolPersist Persist/unpersist ifconfig-pool data to file, at secondsintervals (default=600),
 * @property string    $cipher              Encrypt packets with cipher algorithm alg. The default is BF-CBC,an abbreviation for Blowfish in Cipher Block Chaining mode.

 * @property bool|null $authUserPass
 * @property bool|null $authNocache
 * @property string    $authUserPassVerify  Path to login script
 * @property bool|null $duplicateCn         You may need this if everyone is using same certificate
 * @property bool|null $persistKey
 * @property bool|null $persistTun
 * @property bool|null $compLzo             Use fast LZO compression — may add up to 1 byte per packet for incompressible data.
 * @property bool|null $compNoadapt         When used in conjunction with –comp-lzo, this option will disable OpenVPN’s adaptive compression algorithm.
 * @property integer   $verb                Set output verbosity to n(default=1). Each level shows all info from the previous levels: 0,1,2 ... 11
 * @property string    $server              A helper directive designed to simplify the configuration of OpenVPN’s server mode.
 * @property string    $serverBridge        A helper directive similar to --server which is designed to simplify the configuration of OpenVPN’s server mode in ethernet bridging configurations.
