VPN Server (OpenVPN)
OpenVPN is a Virtual Private Network (VPN) package for creating point-to-point encrypted tunnels
between host computers. A VPN allows users to authenticate and connect securely to the internal
business network. Although it is not required, you should install IPTables before installing
OpenVPN.
