Preface

Congratulations on your purchase from the ZyAIR B-5000 Outdoor Access Point & Bridge.

A wireless gateway is an access point and router rolled into one. It is a cost-effect solution to share Internet
access with multiple computers and expand your wired network.

This User’s Guide is designed to guide you through the configuration of your ZyAIR using the web
configurator or the SMT.

OVERVIEW

Part I:

OVERVIEW

This part introduces the main features and applications of the ZyAIR and shows how to access

the web configurator and use the Quick Setup screens for initial configuration.

ZyAIR B-5000 User’s Guide

Chapter 1

Getting to know your ZyAIR

This chapter introduces the main features and applications of the ZyAIR.

1.1 ZyAIR Features

1.1.1 10 Mbps Ethernet Interface

This auto-negotiating feature allows the ZyAIR to detect the speed of incoming transmissions and adjust
appropriately without manual intervention. It allows data transfer of either 10 Mbps in either half-duplex or
full-duplex mode depending on your Ethernet network.

1.1.2 10 Mbps Auto-crossover Ethernet Interface

The LAN interface automatically adjusts to either a crossover or straight-through Ethernet cable.

1.1.3 802.11b Wireless LAN Standard

ZyAIR products containing the letter “B” in the model name, such as ZyAIR B-5000, comply with the

802.11b wireless standard.

The 802.11b data rate and corresponding modulation techniques are as follows. The modulation technique
defines how bits are encoded onto radio waves.

802.11b

Data Rate (Mbps) Modulation

1 DBPSK (Differential Binary Phase Shift Keyed)

5.5 / 11 CCK (Complementary Code Keying)

Getting to know your ZyAIR 1-1

DQPSK (Differential Quadrature Phase Shift Keying

)

ZyAIR B-5000 User’s Guide

The ZyAIR may be prone to RF (Radio Frequency) interference from other 2.4 GHz

devices such as microwave ovens, wireless phones, Bluetooth enabled devices,

and other wireless LANs.

1.1.4 Firewall

The ZyAIR’s firewall provides DoS (Denial of Service) protection. By default, when the firewall is activated,
all incoming traffic from the WAN to the LAN is blocked unless it is initiated from the LAN. The ZyAIR
firewall supports TCP/UDP inspection.

1.1.5 IEEE 802.1x Network Security

The ZyAIR supports the IEEE 802.1x standard to enhance user authentication. Use the built-in user profile
database to authenticate 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.

1.1.6 Wireless LAN MAC Address Filtering

On a local area network (LAN) or other network, the MAC (Media Access Control) address is a wireless
LAN client’s unique hardware number (On an Ethernet LAN, it's the same as your Ethernet address). Your
ZyAIR checks the MAC address of a wireless station against a list of allowed or denied MAC addresses.

1.1.7 WEP Encryption

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting them over the wireless network to
help keep network communications private.

1.1.8 Deny Clients

You can set the ZyAIR to block access for wireless LAN clients that have the SSID set to “any” or
“ANY”.

1.1.9 PPPoE Support (RFC2516)

PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your ISP to use their
existing network configuration with newer broadband technologies such as ADSL. The PPPoE driver on the
ZyAIR is transparent to the computers on the LAN, which see only Ethernet and are not aware of PPPoE thus
saving you from having to manage PPPoE clients on individual computers.

1-2 Getting to know your ZyAIR

ZyAIR B-5000 User’s Guide

1.1.10 Network Address Translation (NAT) /(PAT)

NAT (Network Address Translation - NAT, RFC 1631) or PAT (Port Address Translation) allows the
translation of an IP address used within one network to different IP addresses known within another network.

1.1.11 DHCP (Dynamic Host Configuration Protocol)

DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the
TCP/IP configuration at start-up from a centralized DHCP server. The ZyAIR has built-in DHCP server
capability disabled by default. This can be changed at the initial configuration to enable DHCP. It can assign
IP addresses, an IP default gateway and DNS servers to DHCP clients.

1.1.12 SNMP

SNMP (Simple Network Management Protocol) is a protocol used for exchanging management information
between network devices. SNMP is a member of the TCP/IP protocol suite. Your ZyAIR supports SNMP
agent functionality, which allows a manager station to manage and monitor the ZyAIR through the network.
The ZyAIR supports SNMP version 1 (SNMPv1) and version 2c (SNMPv2c).

1.1.13 Full Network Management

The embedded web configurator is an all-platform web-based utility that allows you to easily access the
ZyAIR’s management settings. Most functions of the ZyAIR are also software configurable via the SMT
(System Management Terminal) interface. The SMT is a menu-driven interface that you can access from a
terminal emulator through the console port or over a telnet connection.

1.1.14 Embedded TFTP Client Address

The ZyAIR’s embedded TFTP Client address facility enables fast firmware upgrades as well as configuration
file backups and restoration.

Web Configurator Overview

This chapter describes how to access the ZyAIR web configurator and provides an overview of its

screens.

2.1 Web Configurator Overview

The web configurator makes it easy to configure and manage the ZyAIR. The screens you see in the web
configurator may vary somewhat from the ones shown in this document due to differences between firmware
versions. The IP address of your computer will need to be set if you are configuring the ZyAIR for the first
time, see Setting Up Your Computer’s IP Address in the appendix of this User’s Guide.

2.2 Accessing the ZyAIR Web Configurator

Step 1. Make sure your ZyAIR hardware is properly connected (refer to the Quick Installation Guide).

Step 2. Prepare your computer to connect to the ZyAIR (refer to Setting Up Your Computer’s IP Address

in the appendix of this User’s Guide).

Step 3. Launch your web browser.

Step 4. Type "192.168.1.1:2000" as the URL.

Step 5. Type the User Name, ‘admin’ is the factory default and Password, “1234” is the factory default

and click OK.

Step 6. You should now see the web configurator Operating Mode screen. Choose whether you want to

use the ZyAIR as an access point or as a bridge (See Quick Installation Guide Applications
section.

 Access Point Application

Internet Service Providers (ISPs) can use the ZyAIR to provide wireless Internet access to users

that are outdoors or in different buildings. A company with many employees working outdoors
can also use the ZyAIR to extend the existing network without expensive network cables.
Wireless stations can move freely anywhere in the coverage area and use resources on the wired
network.

 Wireless Bridge Application

You can use the ZyAIR as a bridge or router to form a wireless point-to-point or point-to­multipoint backbone connection.

With the bridge mode, you configure each ZyAIR to act as either a central bridge or a remote
bridge. For point-to-multipoint applications, all communications between network systems go
through the central bridge.

Select either Access Point or Bridge. Click Apply.
