About L2TP Tunnels
L2TP stands for Layer 2 Tunnelling Protocol, an extension to the PPP protocol. L2TP combines features of two 
other tunneling protocols: PPTP and L2F. Like PPTP, L2TP is a Datalink Encapsulation option in Connection 
Profiles. It is not an option in device or link configuration screens, as L2TP is not a native encapsulation. 
Consequently, the Easy Setup Profile does not offer L2TP datalink encapsulation. See the 
 for information on creating Connection Profiles.
L2TP configuration
To define an L2TP tunnel, navigate to the Add Connection Profile menu from the Main Menu.
