Chapter 13 Interfaces Table 74 Configuration > Network > Interface > WLAN > Add (WPA/WPA2 Security) LABEL DESCRIPTION Radius Server Port Enter the RADIUS server's listening port number (the default is 1812). Radius Server Secret Enter a password (up to 31 alphanumeric characters) as the key to be shared between the external authentication server and the ZyWALL. The key is not sent over the network. This key must be the same on the external authentication server and ZyWALL. ReAuthentication Specify how often wireless stations have to resend user names and Timer passwords in order to stay connected. Idle Timeout Group Key Update Timer Note: If wireless station authentication is done using a RADIUS server, the reauthentication timer on the RADIUS server has priority. The ZyWALL automatically disconnects a wireless station from the wired network after a period of inactivity. The wireless station needs to enter the user name and password again before access to the wired network is allowed. 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 group 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 mode. 13.7 WLAN Interface MAC Filter The MAC filter allows you to give specific wireless clients exclusive access to the ZyWALL (allow association) or block specific devices from accessing the ZyWALL (deny association) based on the devices' MAC addresses. Every IEEE 802.11b or IEEE 802.11g 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. If you set the filter to deny access and add the MAC address of a connected device, the ZyWALL drops the device's connection immediately. However, if you set the filter to allow only the specified MAC addresses, the ZyWALL does not immediately disconnect all connected wireless clients. To display your ZyWALL's MAC filter settings, click Configuration > Network > Interface > WLAN > MAC Filter. The screen appears as shown. ZyWALL USG 300 User's Guide 339
