7.6 MAC Filter
The MAC filter screen allows you to configure the NBG420N to give exclusive access to up to
32 devices (Allow) or exclude up to 32 devices from accessing the NBG420N (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 NBG420N’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 NBG420N default
is 1800 seconds (30 minutes).
