Overview

In computer networking, L2TP (Layer 2 Tunneling Protocol) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It does not provide any encryption or confidentiality by itself. Rather, it relies on an encryption protocol that it passes within the tunnel to provide privacy
L2TP is an App that needs to install into the router in the System->App Center unit.
