The combination of Layer-2 Tunneling Protocol and Internet Protocol Security (L2TP/IPSec) is a highly
secure technology that enables VPN connections across public networks such as the Internet. L2TP/IPSec
provides both a logical transport mechanism on which to transmit PPP frames as well as tunneling or
encapsulation so that the PPP frames can be sent across an IP network. L2TP/IPSec relies on the PPP
connection process to perform user authentication and protocol configuration. With L2TP/IPSec, the user
authentication process is encrypted using the Data Encryption Standard (DES) or Triple DES (3DES)
algorithm.
L2TP/IPSec requires two levels of authentication:
Computer-level authentication with a preshared key to create the IPSec security associations (SAs) to
protect the L2TP-encapsulated data.
User-level authentication through a PPP-based authentication protocol using passwords, SecureID,
digital certificates, or smart cards after successful creation of the SAs.
