What is the purpose of PPTP?
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that 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.
What is PPTP in computing?
(Point-to-Point Tunneling Protocol) A protocol from Microsoft that is used to create a virtual private network (VPN) over the Internet. Remote users can access their corporate networks via an ISP that supports PPTP. PPTP encapsulates all network protocols for transport over IP.
What is PPTP client?
A PPTP connection is very cross-platform compatible. The protocol works on Windows, Linux, macOS, iOS, Android, Tomato, DD-WRT, and other operating systems and devices. PPTP uses GRE (General Routing Encapsulation), TCP port 1723, and IP port 47.
Is PPTP a session layer?

What is PPTP and how does it work?
PPTP uses GRE (General Routing Encapsulation), TCP port 1723, and IP port 47. PPTP supports encryption keys up to 128-bits, and it uses MPPE (Microsoft Point-to-Point Encryption). Tunneling Types Supported by PPTP Voluntary Tunneling – This type of tunneling is initiated by the client, so no ISP or bridge support is required.
What is a general purpose computer?
A general purpose computer is built to perform a variety of tasks, including the most frequent computing tasks, in a reasonably efficiently manner. It can store and execute multiple programs in its internal storage. Personal computers such as tablets, smartphones, notebooks and desktops are examples of general purpose computers.
How is a PPTP tunnel established and managed?
The PPTP tunnel is established by communicating with the peer on TCP port 1723. That connection is then used to establish and manage the encapsulating tunnel to the same peer.
Why is PPTP the most popular VPN protocol?
