Which VPN Protocol Encapsulates PPP Traffic Using the Secure Sockets Layer (

A VPN protocol is a set of technologies that allow two or more computers to communicate over a secure, encrypted connection. There are several different protocols, and each has its own benefits and limitations. One popular protocol is Secure Sockets Layer (SSL), which is often used to encrypt traffic between web servers and browsers. SSL is also used by some VPN providers to encrypt traffic between their servers and clients.

PPP is a data encapsulation protocol used to support remote access and dial-up networking over public networks such as the Internet. PPP uses a variety of protocols to encapsulate and encrypt data packets for transmission over public networks. One of these protocols is the Secure Sockets Layer (SSL), which is a security protocol that provides communications privacy and data security between two devices. SSL uses encryption to protect data from eavesdropping, tampering, and forgery.

VPNs can use either SSL or another VPN protocol, such as IPsec, to encapsulate and encrypt PPP traffic. SSL is more commonly used for VPNs that provide remote access, such as road warriors accessing corporate resources from home or traveling employees using public Wi-Fi hotspots. IPsec is more commonly used for site-to-site VPNs, which connect two LANs (Local Area Networks) across a public network such as the Internet.

VPN Protocols

VPN protocols are the set of rules that govern how your VPN will work. There are many different protocols, and each has its own advantages and disadvantages. The most common VPN protocols are PPTP, L2TP/IPsec, and OpenVPN.


When it comes to VPN protocols, there are a lot of terms bandied about – SSL, TLS, IPsec, L2TP… it can all be very confusing. In this article we’re going to cut through the jargon and explain what these different protocols are and how they work.

SSL/TLS is the most common type of VPN protocol. SSL (Secure Sockets Layer) is a protocol that was originally developed by Netscape in order to provide security for communications over the Internet. TLS (Transport Layer Security) is a more recent version of SSL that contains some additional security enhancements. Both SSL and TLS use encryption in order to prevent eavesdropping and data tampering.

SSL/TLS is typically used in conjunction with another protocol called IPsec (Internet Protocol security). IPsec is a suite of protocols that provide data confidentiality, data integrity, and data authenticity. When used together, SSL/TLS and IPsec provide a high level of security for communications over the Internet.

L2TP (Layer 2 Tunnelling Protocol) is another popular VPN protocol. L2TP is a tunneling protocol that operates at the data link layer (layer 2) of the OSI model. It can be used in conjunction with either SSL/TLS or IPsec for added security.

PPTP (Point-to-Point Tunnelling Protocol) is a older type of VPN protocol that is less secure than either SSL/TLS or L2TP. PPTP uses less processing power than other protocols, which makes it well suited for use on slower computers such as laptops.


IPsec is a protocol that provides security for Internet Protocol (IP) communications by authenticating and/or encrypting each IP packet. IPsec also includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session.

Comparison of VPN Protocols

In this article, we will compare the most common VPN protocols: PPTP, L2TP/IPsec, OpenVPN, IKEv2/IPSec, and SSTP. We will go over the pros and cons of each protocol and which one is the best for certain situations.

SSL/TLS vs. IPsec

PPP traffic can be encapsulated using either the SSL/TLS or IPsec protocols. Each has its own advantages and disadvantages that should be considered when determining which to use.

SSL/TLS is typically used for VPNs that require high security, such as those used by banks and other financial institutions. It is also often used for remote access VPNs, such as those used by employees to access corporate resources. SSL/TLS has the advantage of being widely available and easy to set up. However, it can be slower than IPsec and may not be compatible with all devices.

IPsec is often used for site-to-site VPNs, such as those connecting two offices or data centers. It is also often used for VPNs that require high performance, such as those used by video streaming services. IPsec has the advantage of being very fast and compatible with most devices. However, it can be more difficult to set up than SSL/TLS and may not provide the same level of security.


After researching the different types of VPN protocols, it is clear that PPTP is the best option if you are looking for a protocol that uses the secure sockets layer to encapsulate PPP traffic. PPTP is widely supported by many software and hardware vendors, making it a good choice for compatibility. In addition, PPTP is relatively easy to set up and does not require advanced technical knowledge.
