6.6 802.1x Overview
The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations
and encryption key management. Authentication can be done using the local user database internal to the
ZyWALL or an external RADIUS server for an unlimited number of users.
6.7

RADIUS

RADIUS is based on a client-sever model that supports authentication and accounting, where access point is
the client and the server is the RADIUS server. The RADIUS server handles the following tasks among
others:
•
Authentication
Determines the identity of the users.
•
Accounting
Keeps track of the client's network activity.
RADIUS user is a simple package exchange in which your ZyWALL acts as a message relay between the
wireless client and the network RADIUS server.
Types of RADIUS Messages
The following types of RADIUS messages are exchanged between the access point and the RADIUS server
for user authentication:
•
Access-Request
Sent by an access point requesting authentication.
•
Access-Reject
Sent by a RADIUS server rejecting access.
•
Access-Accept
Sent by a RADIUS server allowing access.
