ReAuthentication
Timer (Seconds)
Specify how often wireless stations have to reenter usernames and passwords in
order to stay connected. Enter a time interval between 10 and 9999 seconds.
If wireless station authentication is done using a RADIUS server, the
reauthentication timer on the RADIUS server has priority.
Idle Timeout
(Seconds)
The ZyWALL 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.
Authentication
Databases
Click RADIUS to go to the RADIUS screen where you can configure the ZyWALL to
check an external RADIUS server.
WPA Group Key
Update Timer
(Seconds)
The WPA Group 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 Group Key Update Timer is also supported in
WPA-PSK mode.
