Radius Authentication; Radius Server Configuration - NETGEAR RT338 Reference Manual

Reference Guide for the Model RT338 ISDN Router

RADIUS Authentication

The Model RT338 router stores up to eight dial-in user profiles. For more than eight users, you can
use an external RADIUS (Remote Authentication Dial-In User Service) server to provide
authentication service for an unlimited number of users. The RADIUS protocol is a
software-based security authentication protocol developed by the IETF RADIUS Working Group.
The RADIUS protocol carries authentication, authorization, and configuration information
between a remote access device and a shared authentication server.

RADIUS Server Configuration

To use RADIUS authentication, you must have a UNIX or Windows NT computer on your
network as the RADIUS server, as well as the RADIUS software itself.
If you are using CLID authentication for the dial-in users, you must edit the dictionary file in the
RADIUS configuration directory (usually /etc/raddb). Using any text editor, add the following
lines to the dictionary file:
# Netgear proprietary attributes
ATTRIBUTE Netgear-Callback-Option
VALUE Netgear-Callback-Option
VALUE Netgear-Callback-Option
VALUE Netgear-Callback-Option
# Callback phone number source
ATTRIBUTE Netgear-Callback-Phone-Source
VALUE Netgear-Callback-Phone-Source
VALUE Netgear-Callback-Phone-Source
These changes add support for CLID authentication, as described in the following section.
