11.4 The MAC Filter Screen

The MAC filter screen allows you to configure the NBG5715 to give exclusive access to devices
(Allow) or exclude devices from accessing the NBG5715 (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.

DESCRIPTION
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.
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 999999
minutes.
Note: If wireless client authentication is done using a RADIUS server, the
reauthentication timer on the RADIUS server has priority.
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 Enable to turn on preauthentication in WAP2.
Otherwise, select Disable.
Enter the IP address of the external authentication server in dotted decimal
notation.
Enter the port number of the external authentication server.
You need not change this value unless your network administrator instructs you
to do so with additional information.
Enter a password (up to 127 alphanumeric characters) as the key to be shared
between the external authentication server and the NBG5715.
The key must be the same on the external authentication server and your
NBG5715. The key is not sent over the network.
The NBG5715 automatically disconnects a wireless client from the wireless and
wired networks after a period of inactivity. The wireless client needs to send the
username and password again before it can use the wireless and wired
networks again. Some wireless clients may prompt users for a username and
password; other clients may use saved login credentials. In either case, there
is usually a short delay while the wireless client logs in to the wireless network
again.
Enter the time in seconds from 0 to 999999.
Click Apply to save your changes back to the NBG5715.
