What is PPTP?
The following is an official explanation of Microsoft (the first draft submitted by Microsoft ):
Point-to-Point Tunneling Protocol (PPTP) is a network protocol thatEnables the secure transfer of data from a remote client to a private enterprise serverBy creating a virtualPrivate Network (VPN) Upload SSTC
, pay attention to the network conditions between two encrypted tunnels. If there is a high latency or a large number of packet loss, select TCP as the underlying protocol, due to the absence of connection and retransmission mechanisms, UDP protocol is inefficient because it requires the upper-layer protocol to be retransmitted. OpenVPN is a pure application-layer VPN protocol based on SSL encryption. It is a type

Application Introduction
The PPTP VPN PC to site mode provides the terminal with a secure tunnel to the Headquarters network. If you are on a business trip, you can connect to the Internet, use the terminal's own VPN client dial-up connection, and establish a secure tunnel for data transmission.

VPN (Virtual Private Network) is no longer a simple encrypted access tunnel, it integrates multiple functions such as access control, transmission management, encryption, route selection, and availability management, and plays an important role in the global information security system.

Point-to-Point Tunneling Protocol (English: point to Point Tunneling Protocol, abbreviated to PPTP) is one way to implement a virtual private network (VPN). PPTP uses Transmission Control Protocol (TCP) to create controlling channels to send control commands and to encapsulate Point-to-Point Protocol (PPP)
