98 Chapter 5 Wireless LAN

The following table describes the wireless LAN security labels in this screen.

Table 38 Wireless: WPA(2)

LABEL DESCRIPTION

Security Mode Choose WPA or WPA2 from the drop-down list box.

WPA Compatible This field is only available for WPA2. Select this if you want the ZyXEL Device to

support WPA and WPA2 simultaneously.

ReAuthentication

Timer (in seconds)

Specify how often wireless stations have to resend usernames and passwords in

order to stay connected. Enter a time interval between 10 and 9999 seconds. The

default time interval is 1800 seconds (30 minutes).

Note: If wireless station authentication is done using a RADIUS

server, the reauthentication timer on the RADIUS server has

priority.

Idle Timeout The ZyXEL Device automatically disconnects a wireless station from the wired

network after a period of inactivity. The wireless station needs to enter the

username and password again before access to the wired network is allowed.

The default time interval is 3600 seconds (or 1 hour).

Group Key Update

Timer

The Group Key Update Timer is the rate at which the AP (if using WPA-PSK key

management) or RADIUS server (if using WPA key management) sends a new

group key out to all clients. The re-keying process is the WPA 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 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.

Accounting Server (optional)

IP Address Enter the IP address of the external accounting server in dotted decimal notation.

Port Number Enter the port number of the external accounting server. The default port number

is 1813.

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 accounting server and the ZyXEL Device.

The key must be the same on the external accounting server and your ZyXEL

Device. The key is not sent over the network.
