ZyWALL 5 User’s Guide
Chapter 28 LAN Setup 423
Follow the instructions in the next table on how to configure the wireless LAN parameters.
Note: The ZyWALL LAN Ethernet and wireless ports can transparently communicate
with each other (transparent bridge).
28.5.1 MAC Address Filter Setup
Your ZyWALL checks the MAC address of the wireless station device against a list of
allowed or denied MAC addresses. However, intruders could fake allowed MAC addresses so
MAC-based authentication is less secure than EAP authentication.
Table 163 Menu 3.5: Wireless LAN Setup
FIELD DESCRIPTION
Enable
Wireless LAN
Press [SPACE BAR] to select Yes to turn on the wireless LAN. The wireless LAN is off
by default. Configure wireless LAN security features such as Mac filters and 802.1X
before you turn on the wireless LAN.
ESSID (Extended Service Set IDentification) The ESSID identifies the AP to which the wireless
stations associate. Wireless stations associating to the Access Point must have the
same ESSID. Enter a descriptive name (up to 32 characters) for the wireless LAN.
Hide ESSID Press [SPACE BAR] to select Yes to hide the ESSID in the outgoing beacon frame so a
station cannot obtain the ESSID through passive scanning.
Channel ID This allows you to set the operating frequency/channel depending on your particular
region. Use the [SPACE BAR] to select a channel.
RTS
Threshold
(Request To Send) The threshold (number of bytes) for enabling RTS/CTS handshake.
Data with its frame size larger than this value will perform the RTS/CTS handshake.
Setting this attribute to be larger than the maximum MSDU (MAC service data unit) size
turns off the RTS/CTS handshake. Setting this attribute to zero turns on the RTS/CTS
handshake. Enter a value between 0 and 2432.
Frag.
Threshold
The threshold (number of bytes) for the fragmentation boundary for directed messages.
It is the maximum data fragment size that can be sent. Enter a value between 256 and
2432.
WEP Select Disable to allow wireless stations to communicate with the access points without
any data encryption.
Select 64-bit WEP or 128-bit WEP to enable data encryption.
Default Key Enter the key number (1 to 4) in this field. Only one key can be enabled at any one time.
This key must be the same on the ZyWALL and the wireless stations to communicate.
Key 1 to Key
4
The WEP keys are used to encrypt data. Both the ZyWALL and the wireless stations
must use the same WEP key for data transmission.
If you chose 64-bit WEP in the WEP Encryption field, then enter any 5 ASCII
characters or 10 hexadecimal characters ("0-9", "A-F").
If you chose 128-bit WEP in the WEP Encryption field, then enter 13 ASCII characters
or 26 hexadecimal characters ("0-9", "A-F").
Note: Enter “0x” before the key to denote a hexadecimal key. Don’t
enter “0x” before the key to denote an ASCII key.
Edit MAC
Address Filter
Press [SPACE BAR] to select Yes and then press [ENTER] to display menu 3.5.1.
When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm…” to
save your configuration, or press [ESC] at any time to cancel.
