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 Section 7.4.1 on page 77 ) if you want to
authenticate wireless users using a RADIUS Server and/or Accounting Server.
