11.4 The MAC Filter Screen
The MAC filter screen allows you to configure the ZyWALL to give exclusive access to
specific devices (
Allow
) or exclude specific devices from accessing the ZyWALL (
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 addresses of the devices to configure this
screen.
To change your ZyWALL’s MAC filter settings, click the

Update Timer
The
Group Key Update Timer
is the rate at which the AP 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
Group Key Update Timer
is also supported in
WPA(2)-PSK
mode.
