Configure L2TP User Authentication
The TMS zl Module can force an L2TP user to authenticate in one of two ways:
■ Locally
See “Configure Local L2TP Authentication” on page 7-163.
■ To an external RADIUS server.
See “Configure L2TP Authentication to an External RADIUS Server” on
page 7-168.
Configure Local L2TP Authentication
When authenticating users to the local database, you must:
1. Create a user group for the L2TP over IPsec users.
2. Add L2TP dial-in users.
Note You can authenticate a maximum of six L2TP users to the TMS zl Module’s
local database. If you need to authenticate more than six L2TP users, configure
L2TP authentication to an external RADIUS server.
Create a User Group. This section includes the basic steps for setting up a
user group. See “Configure User Authentication” in Chapter 4: “Firewall” for
more instructions.
1. In the left navigation bar of the Web browser interface, click Network >
