L2TP Overview

The Layer 2 Tunneling Protocol (L2TP) provides remote users, such as telecommuters, mobile professionals, and personnel in remote branch offices, with dial-in access to a corporate network. L2TP enables users to create a virtual private network (VPN), which uses the existing physical infrastructure of a public network, such as the Internet, but offers the security and exclusivity of a private network.
