xiv Preface
Preface
Congratulations on your purchase from the ZyXEL G-560 802.11g Wireless Access Point.
An access point (AP) acts as a bridge between the wireless and wired networks, extending your existing
wired network without any additional wiring.
This User’s Guide is designed to guide you through the configuration of your ZyXEL G-560 using the web
configurator.
Use the web configurator to configure your ZyXEL G-560. Not all features can be

use the Wizard to set up the G-560.

ZyXEL G-560 User’s Guide
Getting to Know Your G-560 1-1
Chapter 1
Getting to Know Your G-560
This chapter introduces the main features and applications of the G-560.
1.1 Introducing the G-560 Wireless Access Point
The G-560 is an access point (AP) through which wireless stations can communicate and/or access a wired
network. The G-560 adds a wireless LAN to your existing network. It uses IEEE 802.1x, WEP data
encryption, WPA (Wi-Fi Protected Access) and MAC address filtering to give mobile users highly secured
wireless connectivity. Both IEEE802.11b and IEEE802.11g compliant wireless devices can associate with
the G-560.
The G-560 is easy to install and configure.
1.2 G-560 Features
The following sections describe the features of the G-560.
OTIST (One-Touch Intelligent Security Technology)
OTIST allows your G-560 to assign its SSID and security settings (WEP or WPA-PSK) to the ZyXEL
wireless adapters that support OTIST and are within transmission range. The ZyXEL wireless adapters must
also have OTIST enabled.
10/100M Auto-negotiating Ethernet/Fast Ethernet Interface
This auto-negotiating feature allows the G-560 to detect the speed of incoming transmissions and adjust
appropriately without manual intervention. It allows data transfer of either 10 Mbps or 100 Mbps in either
half-duplex or full-duplex mode depending on your Ethernet network.
10/100M Auto-crossover Ethernet/Fast Ethernet Interface
The LAN interface automatically adjusts to either a crossover or straight-through Ethernet cable.
Reset Button
The G-560 reset button is built into the rear panel. Use this button to restore the factory default password.
802.11g Wireless LAN Standard
The ZyXEL wireless products containing the letter “G” in the model name, such as G-560 and G-162,
comply with the IEEE 802.11g wireless standard.

ZyXEL G-560 User’s Guide
1-2 Getting to Know Your G-560
IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE 802.11b radio card
can interface directly with an IEEE 802.11g access point (and vice versa) at 11 Mbps or lower depending on
range.
Wi-Fi Protected Access
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification draft. Key differences
between WPA and WEP are user authentication and improved data encryption.
SSL Passthrough
The G-560 allows SSL connections to go through the G-560. SSL (Secure Sockets Layer) uses a public key
to encrypt data that's transmitted over an SSL connection. Both Netscape Navigator and Internet Explorer
support SSL, and many Web sites use the protocol to obtain confidential user information, such as credit card
numbers. By convention, URLs that require an SSL connection start with “https” instead of “http”.
Wireless LAN MAC Address Filtering
Your G-560 checks the MAC address of the wireless station against a list of allowed or denied MAC
addresses.
WEP Encryption
WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless network to help
keep network communications private.
IEEE 802.1x Network Security
The G-560 supports the IEEE 802.1x standard to enhance user authentication. Use the built-in user profile
database to authenticate up to 32 users using MD5 encryption. Use an EAP-compatible RADIUS (RFC2138,
2139 - Remote Authentication Dial In User Service) server to authenticate a limitless number of users using
EAP (Extensible Authentication Protocol). EAP is an authentication protocol that supports multiple types of
authentication.
Full Network Management
The embedded web configurator is an all-platform web-based utility that allows you to easily access the G-
560’s management settings.
Logging and Tracing
Built-in message logging and packet tracing.
Wireless Association List
With the wireless association list, you can see the list of the wireless stations that are currently using the G-
560 to access your wired network.
