Chapter 31 System Security 321
Once you enable user authentication, you need to specify an external RADIUS server or create
local user accounts on the ZyXEL device for authentication
Dynamic WEP Key
Exchange
This field is activated only when you select Authentication Required in the
Wireless Port Control field. Also set the Authentication Databases field to
RADIUS Only . Local user database may not be used.
Select Disable to allow wireless stations to communicate with the access
points without using Dynamic WEP Key Exchange.
Select
64-bit WEP or 128-bit WEP to enable data encryption.
Up to 32 stations can access the ZyXEL device when you configure Dynamic
WEP Key Exchange.
PSK Type a pre-shared key from 8 to 63 case-sensitive ASCII characters (including
spaces and symbols) when you select WPA-PSK in the Key Management
Protocol field.
WPA Mixed Mode Select Enable to activate WPA mixed mode. Otherwise, select Disable and
configure Data Privacy for Broadcast/Multicast packets field.
WPA Group Key
Update Timer
The WPA Broadcast/Multicast Key Update Timer is the rate at which the AP
(if using WPA-PSK key management) or RADIUS server (if using WPA key
management) sends a new group key out to all clients. The re-keying process
is the WPA equivalent of automatically changing the WEP key for an AP and all
stations in a WLAN on a periodic basis. Setting of the WPA Broadcast/
Multicast Key Update Timer is also supported in WPA-PSK mode. The ZyXEL
device default is 1800 seconds (30 minutes).
Authentication
Databases
The authentication database contains wireless station login information. The
RADIUS is an external server.
When you configure
Key Management Protocol to WPA , the Authentication
Databases must be RADIUS Only .
Select RADIUS Only to have the ZyXEL device just check the user database
on the specified RADIUS server for a wireless station's username and
password.
When you have completed this menu, press [ENTER] at the prompt “Press ENTER to confirm or ESC
to cancel” to save your configuration or press [ESC] to cancel and go back to the previous screen.
