Terminal Servers or Network Access Servers (NASs) whenever a user
logs on and off a dialup Internet service.
Note: This screen is only available if the MAC Authentication Access
Control button on the General Setup screen has been selected.
There are two main sections in the RADIUS server setup dialog:
RADIUS Authentication Setup and RADIUS Accounting Setup
In most cases you will want to set up both, although you do not have to
set up Accounting. The two are almost identical except for the
Authorization Lifetime, which appears only with Authentication.
To set up RADIUS authentication and accounting:
1. Enter values in the RADIUS Authentication and Accounting Server
Setup screen to configure your RADIUS server. Each field on the
screen is explained in more detail below.
Authorization Lifetime -- Authorization lifetime is the length of time
the authorization is valid. Users will need to be-authenticated/re-
authorized after this time expires. You should set this value to the
maximum time you wish a user to be able to use your service without the
need to be re-authenticated.
Shared Secret -- The client file for your RADIUS server contains the IP
address and password for the base station you are setting up. You must
add the IP address and password (shared secret) from this file in the
RADIUS Server Setup screen.
Note: There are separate shared secrets (passwords) for authentication
setup and accounting setup. The shared secret is an ASCII string that
should be between 2 - 32 characters and should not start with a space.
Primary Server IP Address -- In the RADIUS dialog, enter the IP
address for the RADIUS server (the host).
Primary Server Authentication Port -- In the RADIUS dialog, enter
the authentication port (default = 1812) for the RADIUS server (the host).
Secondary Server IP Address -- If you are using a second RADIUS
server for network robustness, enter the IP address of that RADIUS
server.
Primary Server Accounting Port -- In the RADIUS dialog, enter the
accounting port (default = 1812) for the RADIUS server (the host).
