4.4 MAC Filter
The MAC filter screen allows you to configure the ZyXEL Device to give exclusive access to
up to 32 devices (Allow) or exclude up to 32 devices from accessing the ZyXEL Device
(Deny). Every Ethernet device has a unique MAC (Media Access Control) address. The MAC
address is assigned at the factory and consists of six pairs of hexadecimal characters, for
example, 00:A0:C5:00:00:02. You need to know the MAC address of the devices to configure
this screen.
To change your ZyXEL Device’s MAC filter settings, click Network > Wireless LAN >
MAC Filter. The screen appears as shown.
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).
