9.6.3 Restricted Access
The MAC Filter screen allows you to configure the AP to give exclusive access to devices
(Allow Association) or exclude them from accessing the AP (Deny Association).
9.6.4 Hide ZyWALL Identity
If you hide the ESSID, then the ZyWALL cannot be seen when a wireless client scans for local
APs. The trade-off for the extra security of “hiding” the ZyWALL may be inconvenience for
some valid WLAN clients.
9.7 Security Parameters Summary
Refer to this table to see what other security parameters you should configure for each
authentication method/ key management protocol type. You enter manual keys when using
WEP encryption or WPA-PSK. MAC address filters are not dependent on how you configure
these security features.
9.8 WEP Encryption
WEP (Wired Equivalent Privacy) as specified in the IEEE 802.11 standard provides methods
for both data encryption and wireless station authentication. WEP provides a mechanism for
encrypting data using encryption keys. Both the AP and the wireless stations must use the
same WEP key to encrypt and decrypt data. Your ZyWALL allows you to configure up to four
64-bit or 128-bit WEP keys, but only one key can be used at any one time.
