ZyAIR B-2000 Wireless LAN Gateway with 4-Port Switch

Chapter 1

Getting To Know Your ZyAIR

This chapter describes the key features and applications of your ZyAIR.

1.1 ZyAIR B-2000 Wireless LAN Gateway with 4-Port Switch

The ZyAIR is a cost effective wireless LAN gateway with an integrated 10/100 Mbps and wireless
interfaces and robust network management features for Internet access via an external cable/xDSL modem.
Equipped with a 10Mbps Ethernet WAN port, four auto-negotiating 10/100Mbps Ethernet LAN ports and
the Single User Account (SUA) feature, the ZyAIR is uniquely suited as a broadband Internet access­sharing gateway for multi-computer homes and home offices.

For added security, your ZyAIR supports various methods of network security: WEP, MAC address
filtering, and IEEE 802.1x authentication.

ZyAIR provides ease of installation and superior network security. What’s more, users enjoy the
convenience and mobility with wireless LAN connectivity, working anywhere within the coverage area.

1.2 Features of the ZyAIR

Your ZyAIR is packed with a number of features that give it the flexibility to provide a complete
networking solution for almost any user.

4-Port Switch

A combination of switch and router makes your ZyAIR a cost-effective and viable network solution. You
can connect up to four computers to the LAN ports on you ZyAIR without the cost of a hub.

10/100M Auto-negotiation Ethernet/Fast Ethernet Interface

This auto-negotiation 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 or 100 Mbps in either
half-duplex or full-duplex mode depending on your Ethernet network.

IEEE 802.11b 11 Mbps Wireless LAN

The 11 Mbps wireless LAN provides wireless mobility and a fast network environment for small and home
offices. Computers with IEEE 802.11b wireless NICs (Network Interface Cards) can connect to the local
area network without any wiring efforts and enjoy reliable high-speed connectivity.

Getting To Know Your ZyAIR 1-1

ZyAIR B-2000 Wireless LAN Gateway with 4-Port Switch

Wireless LAN MAC Address Filtering

MAC Address Filtering together with ESSID (Extended Service Set IDentifier), WEP (Wired Equivalent
Privacy) and IEEE 802.1x to ensure wireless network security.

IEEE 802.1x for Network Security

Your ZyAIR supports the IEEE 802.1x standard that works with the IEEE 802.11 to enhance user
authentication. With the local user profile, the ZyAIR allows you to configure up 32 user profiles without a
network authentication server. In addition, centralized user and accounting management is possible on an
optional network authentication server.

EAP (RFC2284)

EAP (Extensible Authentication Protocol) supports multiple authentication methods to ensure the highest
security level available.

RADIUS (RFC2138, 2139)

RADIUS (Remote Authentication Dial In User Service) server enables authentication, authorization and
accounting for your wireless network.

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.

PPTP Support

Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of data from a
remote client to a private server, creating a Virtual Private Network (VPN) using a TCP/IP-based network.
PPTP supports on-demand, multi-protocol and virtual private networking over public networks, such as the
Internet. Use PPTP to connect to a broadband modem to achieve access to high-speed data networks via a
familiar "dial-up networking" user interface.

NAT for Single-IP-address Internet Access

The ZyAIR's SUA (Single User Account) feature allows multiple-user Internet access for the cost of a
single IP account. NAT supports popular Internet applications such as MS traceroute, CuSeeMe, IRC,
RealPlayer, VDOLive, Quake, and PPTP. No configuration is needed to support these applications.

Dynamic DNS Support

With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the
host to be more easily accessible from various locations on the Internet. You must register for this service
with a Dynamic DNS client.

1-2 Getting To Know Your ZyAIR

ZyAIR B-2000 Wireless LAN Gateway with 4-Port Switch

DHCP Support

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 enabled by default. It can assign IP addresses, an IP default gateway and DNS servers to DHCP
clients. The ZyAIR also acts as a surrogate DHCP server (DHCP Relay) where it relays IP address
assignment from the actual real DHCP server to the clients.

Multicast

Traditionally, IP packets are transmitted in two ways - unicast or broadcast. Multicast is a third way to
deliver IP packets to a group of hosts. IGMP (Internet Group Management Protocol) is the protocol used to
support multicast groups. The latest version is version 2 (see RFC 2236). The ZyAIR supports versions 1
and 2.
