Techopedia Explains PPTP VPN

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. PPTP is highly insecure, however, so is not typically used by commercial VPN services.
