PPTP VPN Server
PPTP (The Point-to-Point Tunneling Protocol) uses a control channel over TCP and a GRE tunnel operating to
encapsulate PPP packets. The intended use of this protocol is to provide security levels and remote access levels
comparable with typical VPN products.

and password to authenticate the remote system.
