The following table describes the labels in this screen.
Table 27 Wireless: WPA/WPA2
LABEL DESCRIPTION
WPA Compatible This check box is available only when you select WPA2-PSK or WPA2 in the
Security Mode field.
Select the check box to have both WPA2 and WPA wireless clients be able to
communicate with the ZyXEL Device even when the ZyXEL Device is using
WPA2-PSK or WPA2.
ReAuthentication
Timer (in seconds)
Specify how often wireless stations have to resend usernames and passwords in
order to stay connected. Enter a time interval between 10 and 9999 seconds.
The default time interval is 1800 seconds (30 minutes).
Note: If wireless station authentication is done using a RADIUS
server, the reauthentication timer on the RADIUS server
has priority.
Idle Timeout The ZyXEL Device automatically disconnects a wireless station from the wired
network after a period of inactivity. The wireless station needs to enter the
username and password again before access to the wired network is allowed.
The default time interval is 3600 seconds (or 1 hour).
Group Key Update
Timer
The Group Key Update Timer is the rate at which the AP (if using WPA-PSK/
WPA2-PSK key management) or RADIUS server (if using WPA/WPA2 key
management) sends a new group key out to all clients. The re-keying process is
the WPA/WPA2 equivalent of automatically changing the WEP key for an AP
and all stations in a WLAN on a periodic basis. Setting of the Group Key Update
Timer is also supported in WPA-PSK/WPA2-PSK mode. The ZyXEL Device
default is 1800 seconds (30 minutes).
Authentication Server
IP Address Enter the IP address of the external authentication server in dotted decimal
notation.
Port Number Enter the port number of the external authentication server. The default port
number is 1812.
You need not change this value unless your network administrator instructs you
to do so with additional information.
Shared Secret Enter a password (up to 31 alphanumeric characters) as the key to be shared
between the external authentication server and the ZyXEL Device.
The key must be the same on the external authentication server and your ZyXEL
Device. The key is not sent over the network.
Accounting Server
Active Select Yes from the drop down list box to enable user accounting through an
external authentication server.
IP Address Enter the IP address of the external accounting server in dotted decimal notation.
Port Number Enter the port number of the external accounting server. The default port number
is 1813.
You need not change this value unless your network administrator instructs you
to do so with additional information.
Shared Secret Enter a password (up to 31 alphanumeric characters) as the key to be shared
between the external accounting server and the ZyXEL Device.
The key must be the same on the external accounting server and your ZyXEL
Device. The key is not sent over the network.
