For OpenVPN to work as a server, you will need to do the following: 1) Create configuration file in #{etc}/openvpn, samples can be found in #{share}/doc/openvpn 2) Install the launchd item in /Library/LaunchDaemons, like so: sudo cp -vf #{prefix}/org.openvpn.plist /Library/LaunchDaemons/. sudo chown -v root:wheel /Library/LaunchDaemons/org.openvpn.plist 3) Start the daemon using: sudo launchctl load /Library/LaunchDaemons/org.openvpn.plist Next boot of system will automatically start OpenVPN.
