Figure 1-1 Secure Wireless Connection - ZyXEL Communications Vantage RADIUS 50 User Manual

Client usernames and passwords are forwarded from a wireless network to Vantage RADIUS, which then
validates them against its own list. This ensures that only individuals with valid accounts will be granted
network access.
The following gives an overview of Vantage RADIUS' role in a network.
•
Wireless station A attempts to communicate with B over the wireless network via C.
•
C sends a "request identity" message to A for authentication.
•
A replies with identity information, including username and password.
•
C communicates with Vantage RADIUS, which checks the user information against its list of valid
accounts and determines whether or not to authenticate A.
•
A is authenticated and can communicate with B over the wireless network.
1.3.2 Remote RADIUS Authentication
Vantage RADIUS can forward authentication for user accounts to other remote or proxy RADIUS servers
behind the local Vantage RADIUS. With remote RADIUS servers, wireless client authentication can be
easily managed and more wireless clients can be authenticated. These remote RADIUS servers can be other
Vantage RADIUS' or a RADIUS server computer (for example, Windows 2003 IAS).
