Wireless LAN Security Setup
This chapter describes the types of security you can enable on the ZyWALL. Wireless LAN is
available on the ZyWALL 10W and 100 models.
7.1 Levels of Security
Wireless security is vital to your network to protect wireless communication between wireless clients, access
points and other wireless.
The figure below shows the possible wireless security levels on your ZyWALL. The highest security level is
EAP (Extensible Authentication Protocol) authentication. 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 clients.
Figure 7-1 ZyWALL Wireless Security Levels
If you do not enable any wireless security on your ZyWALL, your network is accessible to any wireless
networking device that is within range.
Use the ZyWALL web configurator to configurator to set up your wireless LAN security settings. Refer to
the chapter on using the ZyWALL web configurator to see how to access the web configurator.
7.2 Data Encryption with WEP
WEP encryption scrambles the data transmitted between the wireless clients and the access points to keep
network communications private. It encrypts unicast and multicast communications in a network. Both the
wireless clients and the access points must use the same WEP key for data encryption and decryption. For
wireless LAN setup, refer to section 6.6.
