Wireless LAN
This chapter discusses how to configure wireless LAN on the ZyWALL.
9.1 Wireless LAN Introduction
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 Appendix A on page 660 for how to install a WLAN card.
See the WLAN appendix for more detailed information on WLANs.
9.1.1 Additional Installation Requirements for Using 802.1x
• 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.
9.2 Configuring WLAN
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
Figure 80 on page 187 ) 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.
