3.2.3.3 L2TP
In computer networking, Layer 2 Tunneling Protocol (L2TP) 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.
The Business Security Gateway can behave as a L2TP server and a L2TP client at
the same time.
