RADIUS Screen
8.1  Overview
This chapter describes how you can use the Wireless > RADIUS screen.
Remote Authentication Dial In User Service (RADIUS) is a protocol that can be used to 
manage user access to large networks. It is based on a client-server model that supports 
authentication, authorization and accounting. The access point is the client and the server is 
the RADIUS server. 
Figure 42   RADIUS Server Setup
In the figure above, wireless clients A and B are trying to access the Internet via the ZyXEL 
Device. The ZyXEL Device in turn queries the RADIUS server if the identity of clients A and 
U are allowed access to the Internet. In this scenario, only client U’s identity is verified by the 
RADIUS server and allowed access to the Internet.  
8.2  What You Can Do in the RADIUS Screen
Use the Security > RADIUS screen (see 
wireless users using
 
a RADIUS Server and/or Accounting Server.
8.3  What You Need to Know About RADIUS
The RADIUS server handles the following tasks:
• Authentication which determines the identity of the users.
• Authorization which determines the network services available to authenticated users 
once they are connected to the network.
