Chapter 6 Wireless Lan; Introduction; Additional Installation Requirements For Using 802.1X; Wireless Security - ZyXEL Communications ZyWall 70 User Manual

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

6.1 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 the Hardware Specifications appendix for how to install a WLAN card.
See the WLAN appendix for more detailed information on WLANs.

6.1.1 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.

6.2 Wireless Security

Wireless security is vital to your network to protect wireless communication between wireless
stations, access points and other wireless.
The figure below shows the possible wireless security levels on your ZyWALL. EAP
(Extensible Authentication Protocol) is used for authentication and utilizes dynamic WEP key
exchange. It requires interaction with a RADIUS (Remote Authentication Dial-In User
Service) server either on the WAN or your LAN to provide authentication service for wireless
stations.
