How to install and configure PPTP on cPanel server.

PPTP – Point-to-Point Tunneling Protocol – extends the Point-to-Point Protocol (PPP) standard for traditional dial-up networking. Which enables the secure transfer of data from a remote client to a private enterprise server by creating a virtual private network (VPN) across TCP/IP-based data networks. PPTP supports on-demand, multi-protocol, virtual private networking over public networks, such as the Internet.
