7.4.5 MAC Filter

This screen allows you to configure the ZyXEL Device to give exclusive access to
specific devices (Allow) or exclude specific 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 addresses of the devices to configure this screen.

DESCRIPTION
This field is available only when you select WPA2.
Pre-authentication enables fast roaming by allowing the wireless
client (already connecting to an AP) to perform IEEE 802.1x
authentication with another AP before connecting to it. Select
Enabled to turn on preauthentication in WAP2. Otherwise, select
Disabled.
This field is available only when you select WPA2.
Specify how often wireless clients have to resend usernames and
passwords in order to stay connected. Enter a time interval between
10 and 2147483647 seconds.
Note: If wireless client authentication is done using a RADIUS
server, the reauthentication timer on the RADIUS server
has priority.
The Group Key Update Timer is the rate at which the AP (if using
WPA(2)-PSK key management) or RADIUS server (if using WPA(2)
key management) sends a new group key out to all clients. The re-
keying process is the WPA(2) 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. The ZyXEL Device default is 1800 seconds (30
minutes).
Enter the IP address of the external authentication server in dotted
decimal notation.
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.
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.
