PPTP VPN is the process of creating and managing VPN connections or services using point-to-point tunneling protocol (PPTP). It is one of the most common ways of creating a VPN connection, and operates at layer 2 of the OSI model.
PPTP VPN is also known as VPN over PPTP.
PPTP VPN primarily enables network traffic through different protocols to be sent over a P-based network. The PPTP VPN is created using a client/server architecture where PPTP VPN clients connect with a server to gain VPN access. It uses TCP and generic routing encapsulation (GRE) to enable VPN communication, encryption and encapsulation.
PPTP VPN generally utilizes TCP port 1723 to create a tunnel and connect with a peer and further utilize this connection to create a GRE tunnel on the same peer to enable encapsulation. PPTP VPN can be used to create remote access and site-to-site VPN connections.
