About PPTP
Point-to-Point Tunneling Protocol (English: point to Point Tunneling Protocol, abbreviated to PPTP) is one way to implement a virtual private network (VPN). PPTP uses Transmission Control Protocol (TCP) to create controlling channels to send control commands and to encapsulate Point-to-Point Protocol (PPP) packets to send data using the generic Routing Encapsulation (GRE) channel. This agreement was first developed by manufacturers such as

Data transfer phase
Once this 4-phase negotiation is complete, PPP begins forwarding data between the connecting peers. Each transmitted datagram is encapsulated within the PPP header, which is removed after it arrives at the receiving party. If you choose to use data compression in Phase 1 and you have completed the negotiation in Phase 4, the data will be compressed bet
