Chapter 9 Wireless LAN

170

This chapter discusses how to configure wireless LAN on the ZyWALL.

A wireless LAN can be as simple as two computers with wireless LAN adapters 
communicating in a peer-to-peer network or as complex as a number of computers with 
wireless LAN adapters communicating through access points which bridge network traffic to 
the wired LAN. 

Note: See 

 for how to install a WLAN card.

See the WLAN appendix for more detailed information on WLANs.

• A computer with an IEEE 802.11b wireless LAN card. 
• A computer equipped with a web browser (with JavaScript enabled) and/or Telnet.
• A wireless station must be running IEEE 802.1x-compliant software. Currently, this is 

offered in Windows XP. 

• An optional network RADIUS server for remote user authentication and accounting.

The WLAN interface uses the ZyWALL's WLAN IP address and the MAC address of the 
WLAN card. You need to insert a compatible wireless LAN card and enable the card in the 
Wireless Card screen (see 

) to have wireless functionality. You can also 

use the Port Roles screen to set a port to be part of the WLAN and connect an access point 
(AP) to the WLAN interface to extend the ZyWALL’s wireless LAN coverage. 

There is a WLAN interface in the firewall. You can specify firewall rules for traffic going to or 
from the WLAN.

Click NETWORK, WLAN to open the WLAN screen to configure the IP address for 
ZyWALL’s WLAN interface, other TCP/IP and DHCP settings.
