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.
