12.2 RADIUS 

Support

This section shows you to configure user authentication and accounting using an external RADIUS server.

12.2.1 About RADIUS

RADIUS (Remote Authentication Dial-In User Service) is a client/server protocol that enables remote access
servers to communicate with a central server to authenticate dial-in users. RADIUS allows a company to maintain
user profiles in a central database that all remote servers can share.

12.2.2  Using RADIUS Authentication

12.3 RADIUS 

Authentication

Your Prestige has a built-in dial-up user list; however, the number of users that can be stored locally is limited due
to memory constraints.  If you have more users than what the Prestige can store locally, use an external RADIUS
(Remote Authentication Dial-In User Service) server that provides authentication service for unlimited number of
users.

12.3.1  Installing a RADIUS Server

To use RADIUS authentication, you need to have a UNIX or Windows NT machine on your network as the
RADIUS server, as well as the RADIUS software itself.

You can obtain the RADIUS server software, along with documentation, at

 or

Follow the included instructions to install the software on your server.

After you install the server software, you will need to edit the 

dictionary

 file in the RADIUS configuration

directory (usually 

/etc/raddb

). Using any text editor, add the following lines to the 

dictionary

 file:

# Zyxel proprietary attributes
ATTRIBUTE  Zyxel-Callback-Option  192  int0eger
VALUE      Zyxel-Callback-Option  None       0

VALUE      Zyxel-Callback-Option  Optional   1

# Callback phone number source
ATTRIBUTE  Zyxel-Callback-Phone-Source  193  integer

VALUE      Zyxel-Callback-Phone-Source  Preconfigured  0

VALUE      Zyxel-Callback-Phone-Source  User           1
