Point-to-Point Tunneling Protocol

The Point-to-Point Tunneling Protocol (PPTP) is an obsolete method for implementing virtual private networks. PPTP has many well known security issues. PPTP uses a TCP control channel and a Generic Routing Encapsulation tunnel to encapsulate PPP packets. Many modern VPNs use various forms of UDP for this same functionality. The PPTP specification does not describe encryption or authentication features and relies on the Point-to-Point Protocol being tunneled to implement any and all security functionalities. The PPTP implementation that ships with the Microsoft Windows product families implements various levels of authentication and encryption natively as standard features of the Windows PPTP stack. The intended use of this protocol is to provide security levels and remote access levels comparable with typical VPN products. (Wikipedia).

constructing a perpendicular line through a point (on the line) - geometry constructions

In this video, I show how to construct a perpendicular line through a point on the line. I use a compass and straightedge to construct the perpendicular line. The technique used in video is similar to the construction of a perpendicular bisector. Outside of this computer software, this is
