What Is PPTP: Point-to-Point Tunneling Protocol.
PPTP was designed to improve on its predecessor Point-to-Point Protocol, a data link layer Layer 2 protocol designed to connect two routers directly. While it's' considered a fast and stable protocol for Windows networks, PPTP is no longer considered secure. PPTP has been superseded by safer and more secure VPN tunneling protocols, including OpenVPN, L2TP/IPSec, and IKEv2/IPSec. How PPTP Works. PPTP is an outgrowth of PPP, and as such, is based on its authentication and encryption framework. Like all tunneling technologies, PPTP encapsulates data packets, creating a tunnel for data to flow across an IP network. PPTP uses a client-server design the technical specification is contained in Internet RFC 2637 that operates at Layer 2 of the OSI model. Once the VPN tunnel is established, PPTP supports two types of information flow.: Control messages for managing and eventually tearing down the VPN connection. Control messages pass directly between VPN client and server.
