Group Key Update

 

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

 

 

Timer

 

WPA2-PSKkey 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-PSKmode. 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

 

 

 

 

 

 

 

Active

 

Select Yes from the drop down list box to enable user accounting through an

 

 

 

 

external authentication server.

 

 

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.

4.4 OTIST

In a wireless network, the wireless clients must have the same SSID and security settings as the access point (AP) or wireless router (we will refer to both as “AP” here) in order to associate with it. Traditionally this meant that you had to configure the settings on the AP and then manually configure the exact same settings on each wireless client.

OTIST (One-Touch Intelligent Security Technology) allows you to transfer your AP’s SSID and WEP or WPA-PSK security settings to wireless clients that support OTIST and are within transmission range. You can also choose to have OTIST generate a WPA-PSK key for you if you didn’t configure one manually.

Note: OTIST replaces the pre-configured wireless settings on the wireless clients.
