L2TP, SSTP, PPTP and OpenVPN.

Today, various VPN protocols are being used. These include L2TP/IPSec, PPTP and OpenVPN.

L2TP/IPSec is the most modern protocol and the one used by default in many commercial VPN services. L2TP is an abbreviation of Layer 2 Tunneling Protocol. IPSec is Internet Protocol Security and is the security technology used to implement L2TP.

VPN protocol – What are the differences between various VPN protocols? Which one is the best to use? I want you to be fully informed and make an educated decision when deciding on a VPN protocol. Therefore, in this article, you will find explained what are the differences between L2TP/IPSec, PPTP and OpenVPN.

L2TP/IPSec is a protocol for Point-to-Point Tunneling. This protocol is used by major VPN providers such as HideMyAss, IPVanish, PureVPN, Private Internet Access, StrongVPN and TorGuard.L2TP basically creates a tunnel between two endpoints (for example an L2TP client located in your home and a server located in the US). This tunnel then allows other protocols to be run through it (like IPSec).

Each protocol has its own specific use. In this article, I will explain the differences between the most popular protocols, so that you can better understand what is important to know to find a VPN connection that best suits your needs. I will also explain why it is important to choose a VPN service with support for OpenVPN protocol.

There are several things to consider when choosing a VPN protocol. The brand of VPN service is one factor and we have already written about the best VPN service brands and the best VPN encryption.

The devices you will be using with VPN are also an important factor. For example, on Windows laptops, OpenVPN is a popular option. However, PPTP may be better on iOS devices because it is available for iOS devices (PPTP is not available for Windows). L2TP/IPSec works with all the devices but it may not be used on public WiFi networks due to security reasons (L2TP/IPSec use passwords rather than certificates). Finally, there are VPN protocols that are more secure than others. This refers to the encryption standard being used and the strength of the keys used in the encryption.

PPTP

In addition to the already available protocols in the PPTP protocol, IKE (Internet Key Exchange) support is added. The PPTP protocol implements the OSI layer two services: transparent data transfer through the tunnel and remote access to a dial-up server, using an analogue modem.

The Point-to-Point Protocol (PPP) provides a reliable way to establish a connection between remote communication nodes. The computer that initiates the connection is called the gateway and is connected to the network provider, and the communication node that connects is called a remote node and is connected to the client-side.

To provide remote access to another communication node, the gateway sends it the information required to establish a connection.

To provide security for authentication during communication sessions, IPsec mechanisms are used in combination with Point-to-Point Tunneling Protocol (PPTP).

L2TP

L2tp is a tunnelling protocol over the internet. It provides strong authentication and secure data transmission with the help of IPSec. The L2tp tunnelling protocol is used for protecting your IP packet from possible attacks and transferring information at a high-speed over long distances. While using L2tp, the transport layer of the OSI model encrypts all the information packets with the help of IPSec to provide security and privacy and prevent active attacks. This process makes it impossible for anyone to read or change your data. The L2tp tunnelling protocol can be used for various purposes such as VPN (Virtual Private Network), L2tp VPN (Virtual Private Network – L2tp), PPTP vs L2tp (PPTP vs. L2tp), L2tp Pptp Comparison (L2tp Pptp Comparison).

SSTP

that it is more secure and more reliable for sending data across the internet via your computer than the standard SSL based VPN. sstp VPN is created, designed, and maintained by a global network of dedicated servers that offer high performance and high security. sstp is created for those users who are looking to combine the security benefits of an SSL based VPN with the high performance, lower latency, and lower jitter of a TCP connection.

The SSTP is a tunnelling protocol that provides encapsulation of Point to Point Protocol (PPP) packets within Internet Protocol security (IPsec) packets. This protocol is provided as an alternative to the Layer 2 Tunneling Protocol (L2TP). It enables a VPN connection over the Internet or using an Internet connection without having to establish a dedicated virtual circuit. L2TP is a protocol that can be run on top of either the User Datagram Protocol (UDP) or the Transmission Control Protocol (TCP). The SSTP was created by Microsoft as an evolution of the PPTP protocol.

OpenVPN

is a free and open-source software application that implements virtual private network (VPNs) techniques to create private network connections across shared or public networks such as the internet.

The OpenVPN protocol is an extension of the OpenVPN project. It provides support of multiple simultaneous VPNs, client-side authentication, and management interface through a single control channel. The latter feature is used to implement the login server, status server and other management functions.
