office, Home office). Therefore, all the wireless LAN subscribers must know the PSK, be-

cause it is used to generate the session key.

WPA2

WPA2 is the enhancement of WPA. In WPA2, the 802.11i standard is not only implemen-

ted for the first time in full, but another encryption algorithm AES (Advanced Encryption

Standard) is also used.

Access control

You can control which clients can access your wireless LAN via your device by creating an

Access control list (ACL Mode or MAC Filter). In the Access Control List, you enter the

MAC addresses of the clients that may access your wireless LAN. All other clients have no

access.

Security measures

To protect the data transferred on the WLAN, you may need to carry out the following con-

figuration steps in the Wireless LAN -> WLAN -> Wireless Networks (VSS)->New->/

menu:

• Change the access passwords for your device.

• Change the default SSID, Network Name (SSID) =  , of your access

point. Set Visible = 0#2. This will exclude all WLAN clients that attempt to establish

a connection with the general value for Network Name (SSID) - and do not know the

SSID settings.

• Use the available encryption methods. To do this, select Security Mode = 0 &, 0

& ,   or  0"!  or both, and enter the relevant key in the access

point under WEP Key1 - 4 or Preshared Key and in the WLAN clients.

• The WEP key should be changed regularly. To do this, change the Transmit Key. Select

the longer 104 Bit WEP key.

• For the transfer of highly security-critical informationen, Security Mode = 

0"!  should be configured with WPA Mode =  . This method contains

hardware-based encryption and RADIUS authentication of the client. In special cases,

combination with IPSec is possible.

• Restrict WLAN access to permitted clients. Enter the MAC addresses of the wireless net-

work cards of these clients in the Allowed Addresses-list in the MAC Filter menu (see

Fields in the MAC Filter menu on page 161).

In the Wireless LAN -> WLAN -> Virtual Service Sets menu, a list of all WLAN networks
