Defining L2TP / IPSec pre-shared Phrase
The configuration of L2TP with IPSec requires that all VPN clients and gateways use the
same pre-shared key (or “phrase”). If the pre-shared phrase is changed because it has been
compromised, you must manually change the phrase on each device that uses a pre-shared
phrase to connect to the VPN gateway. A pre-shared phrase can be up to 256 characters.
The longer and more complex the phrase, the harder it is to guess.
Using the VPN – PPTP / L2TP User Configuration menu, you can define the pre-shared
phrase that the Gateway uses.
1. Click
VPN
in the menu bar.
2. On the VPN menu, uncheck one of the following options and click
Apply
(see Figure 83).
Otherwise, the buttons for adding, editing, and deleting the VPN – PPTP / L2TP
configurations on the VPN – PPTP / L2TP User Configuration menu will be unavailable.

Disable PPTP VPN Functions
–
Disable L2TP over IPsec VPN Functions
3. In the menu bar, under
VPN
