Chapter 7 Wireless LAN The following table describes the wireless LAN security labels in this screen. Table 25 Wireless LAN > General: WPA(2) LABEL DESCRIPTION Security Mode Choose WPA or WPA2 from the drop-down list box. Active Compatible This field is only available for WPA2. Select this if you want the ZyXEL Device to support WPA and WPA2 simultaneously. Encryption Select the encryption type (TKIP, AES or TKIP+AES) for data encryption. WPA2 Preauthenticatio n 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. Network Re-auth Interval 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. Group Key Update Timer 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 rekeying 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). Authentication Server IP Address Enter the IP address of the external authentication server in dotted decimal notation. Port Number 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. Shared Secret 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. 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 P-870H/HW Series User's Guide 95
