A remote access virtual private network (VPN) enables users who are working remotely to securely access and use applications and data that reside in the corporate data center and headquarters, encrypting all traffic the users send and receive.
What is L2TP tunneling?
L2TP (Layer 2 Tunneling Protocol) is an encapsulation protocol that, while not providing any confidentiality or authentication by itself, relies on an IPSec encryption protocol to provide privacy to remote network users. L2TP connections, also known as virtual lines, provide inexpensive access for remote users as it enables the corporate network server to manage the IP addresses assigned to their remote users. In this way, L2TP can guarantee confidentiality, authentication and integrity.
Why do companies use VPNs?
Numerous companies today interconnect their users and branch offices through VPNs, because in addition to having low implementation and maintenance costs, it offers high integrity and reliability of the data trafficked.
What is SSL VPN?
SSL VPN (Secure Sockets Layer) is a format that can be used in two ways, some solutions offer direct web access without the need to install a connection client, and others, via client. The basis of information transport through SSL and its sub-protocols, ensuring communication and security between the points involved. This type of VPN has gained a growing number of users because of the ease of use and interoperability with mobile devices, which are increasingly being used by employees in transit who need to securely access company information.
What is a connection protocol?
Connection protocol that can: negotiate and establish a connection between the two computers; use an authentication protocol, such as PAP or CHAP, to authenticate a client to the remote system; support several types of Network layer protocols that might use the connection; encrypt the transmissions, although PPP encryption is considered weak by today's standards.

A router or remote access server with VPN software installed and encrypts and encapsulates data to exchange over the tunnel.
What is Layer 2 protocol?
A Layer 2 protocol developed by Microsoft that encapsulates PPP data frames so that the frame can traverse the Internet masked as an IP transmission. It uses TCP segments at the Transport layer and supports the encryption, authentication, and access services provided by RRAS. Users can either directly contact an RRAS access server that's part of the VPN, or they can access their ISP's remote access server first, then connect to a VPN.

Point-To-Point Protocol
- PPP is a remote access protocol that allows you to implement TCP/IP. It establishes a connection via point-to-point links (i.e., dedicated leased lines and dial-up). PPP is used most often for remote connections to LANs and ISPs. PPP utilizes the Link Control Protocol (LCP), which tests the link between client and PPP host and specifies PPP client configuration, to communicate between h…
Point-To-Point Tunneling Protocol
- PPTP is a remote access protocol, based on PPP, created by Microsoft. It’s used to establish virtual connections across the internet via PPP and TCP/IP, enabling two networks to use the internet as their WAN link while retaining the security benefits of a private network. PPTP is a great option because it’s simple and secure. To use PPTP, you’ll ha...
