What is VPN?

A virtual private network (VPN) is a computer network that is layered on top of an underlying computer network. The private nature of a VPN means that the data traveling over the VPN is not generally visible, or is encapsulated from, the underlying network traffic. Similarly, the traffic within the VPN appears to the underlying network as just another traffic stream to be passed.

What is PPTP?

The Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. PPTP uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets. The PPTP specification does not describe encryption or authentication features and relies on the PPP protocol being tunneled to implement security functionality. However the most common PPTP implementation, shipping 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 similar levels of security and remote access as typical VPN products.
