VPN technologies make use of tunneling protocols to establish the connection and encryption protocols to furnish privacy, enabling the remote user to access a VPN server securely on the company network. In case of internet-based VPNs, the VPN protocols conceal the basic switching and routing infrastructure of the internet from both the sender and the receiver. VPN for PPTP protocol also supports encryption and authentication to have the tunnels secure. A VPN supports two basic types of tunneling: voluntary tunneling and compulsory tunneling.
Different types of tunneling protocols are being used to offer security over the internet. The important question is about which VPN technology should you use. There are four most common protocols or methods for deploying or creating a VPN. These are as follows:
- Point-to-Point tunneling protocol (PPTP)
- Layer-2 tunneling protocol (L2TP)
- IP security (IPSec)
- Secure sockets layer (SSL)
Among these protocols, the VPN for PPTP protocol is the most commonly used type.
PPTP Protocol
The point-to-point tunneling protocol (PPTP) was originally founded by Microsoft in affiliation with other technology companies like 3COM, US Robotics, ECI Telematics, and Ascend. It is the most extensively supported VPN protocol among Windows users and is the only protocol that is integrated into Windows NT and 9x operating systems. A VPN for PPTP protocol supports 40-bit and 128-bit encryption and is an adjunct of the standard point-to-point protocol (PPP). The PPTP protocol makes use of a mutated version of the General Routing Encapsulation (GRE) protocol to transfer data from and to its final destination. This provides PPTP the flexibility of managing protocols apart from IP, such as NetBEUI or Internet Packet Exchange (IPE).
VPN for PPTP protocol are the most common form of VPN used. VPN tunnels are usually established through the following two step process:
- The PPTP client uses the PPP dial-up networking to connect to the ISP (ISDN or traditional modem).
- PPTP protocol develops a TCP connection control to create a tunnel between the VPN servers through the network device.
PPTP protocol also supports the connectivity of VPN through a LAN. In such cases, there is no need for an ISP connection and therefore tunnels can be created directly.
A VPN for PPTP protocol is a relatively popular choice especially as it does not need any additional client software to operate on. This protocol is already a built-in feature in a majority of operating systems, inclusive of Microsoft Windows, Mac OS X, Linux, iOS, and Android OS. The set up and usage of a VPN for PPTP protocol is also extremely easy. If you always access the internet on your mobile device, then PPTP VPN protocol is the best solution for your online privacy, security and anonymity.
