How To Install PPTP VPN on CentOS 7

How To Install PPTP VPN on CentOS 7? A virtual private network (VPN) is network that extends a private network (i.e. LAN) across a public network, such as the Internet. It enables a communications between computers and devices across shared or public networks as if it were directly connected to the private network, while benefiting from the functionality, security and management policies of the private network.

This is done by establishing a virtual point-to-point connection through the use of dedicated connections, encryption, or a combination of the two.
