vi IBM®High Rate Wireless LAN Gateway: User’s Guide

Part 1: Product description

The IBM High Rate Wireless LAN Gateway provides small offices and home

offices (SOHO) an economical way to connect an entire local area network

(LAN) to the Internet using an external DSL/Cable modem. With its built-in

wireless access point, you can connect your IEEE 802.11b-compliant mobile

computers or other clients to establish a home network.

The IBM High Rate Wireless LAN Gateway has the following features.

vHigh-speed Internet access: Connect an external DSL/Cable modem to

provide Internet access 10-100 times faster than a 56k modem.

vWireless access point: The IBM High Rate Wireless LAN Gateway contains

an embedded wireless access point that supports the industry standard

(IEEE 802.11b WLAN) protocol with a data rate up to 11 megabits per

second (Mbps), can have up to 63 simultaneous users, and is compatible

with all WiFi IEEE 802.11b-compliant wireless LAN (WLAN) client cards

with seamless roaming between access points.

vBuilt-in switch: With a built-in four-port, dual speed (10/100 Mbps)

Ethernet switch, you get complete and fast connectivity for small offices.

vSingle shared ISP account with network address translation (NAT):NAT

works by translating the data packets’IP address from the one provided by

the Internet service provider (ISP) to the IP address of the computer attached

to the IBM High Rate Wireless LAN Gateway. All computers on the network

can share a single ISP account.

vDynamic host configuration protocol (DHCP): The IBM High Rate Wireless

LAN Gateway provides IP address acquisition and management.

vWeb-based management: The IBM High Rate Wireless LAN Gateway

simplifies web-based management with a built-in, intuitive web-based

configuration and administration graphical user interface (GUI).

vBuilt-in firewall: The IBM High Rate Wireless LAN Gateway has a built-in

firewall to protect the computers on the local network from hackers on the

Internet.

–NAT: NAT hides the IP address of the local network from the Internet.

–Packet filtering: Data packets without a trusted IP address or port are

dropped. For DMZ, the exposed computer receives all packets that would

otherwise be dropped.

–Stateful inspection: Data packets are inspected for relevance within a data

stream or session. If the data packets are not relevant, they are dropped.

For DMZ, the exposed computer receives all packets that would

otherwise be dropped.

vVirtual Server: With the IBM High Rate Wireless LAN Gateway, you can set

up a server on your local network that can be remotely accessed from the

Internet (an ftp server, for example).

vDMZ: The IBM High Rate Wireless LAN Gateway can support some special

applications and Internet games. With DMZ, one designated computer is

removed from behind the built-in firewall and exposed to the Internet. This

speeds up Internet gaming and might be required from special applications.

vAccess control (Packet filtering): The IBM High Rate Wireless LAN

Gateway can monitor and block specific packets or applications. This

function is not the same packet filtering function described for the built-in

firewall. The Administrator can set up IP addresses on the Internet that the

local computers are blocked from accessing. For example, if the

Administrator does not want users to access IP address 255.255.255.255 on

the Internet, this function blocks the address.

The Administrator can also set ports to be blocked from local use. For

example, if the Administrator does not want users to have ftp access to the

Internet, port 21 can be blocked.

vWireless security: As access control mechanisms, the IBM High Rate

Wireless LAN Gateway has ESSID for wireless network segmentation, MAC

address registration, and wireless equivalency protection (WEP) (64- and

128-bit) encryption.

vVirtual private networks (VPN): The IBM High Rate Wireless LAN Gateway

supports the following VPNs:

–IP Security (IPSec) passthrough

–Point-to-point tunneling protocol (PPTP) passthrough

–Point-to-point protocol over Ethernet (PPPoE) for DSL

Note: Functions listed above that are not viewable in the built-in

HTML-configuration utility are active and not adjustable.

vStatus light emitting diodes (LEDs): These LEDs provide a quick method to

check the status of the Gateway.

vInternet-broadband port: The IBM High Rate Wireless LAN Gateway has an

RJ-45 interface to connect, through an Ethernet cable, to a DSL/Cable

modem.

v10BASE-T/100BASE-Tx ports: These ports can automatically detect the

connection speed of a link and provide a 10 or 100 Mbps connection to

Ethernet devices, based on the detected capabilities. All of the 10/100 Mbps

Ethernet ports automatically detect whether the attached Ethernet cable is

wired in standard or crossover configuration. These ports support a

maximum length of 100 m (328.1 ft.) over a Category 5 twisted pair cable.

vPower jack: Connect the included external power adapter to the power jack.

The following items are included in your option package:

vOne IBM High Rate Wireless LAN Gateway unit

1-2 IBM®High Rate Wireless LAN Gateway: User’s Guide

vOne ac power supply

vOne power cord

Note: In the event that your Gateway comes with two power cords, be sure

to use the one labeled for your country. One is labeled for use in the

United States and Canada, and one is labeled for use in Japan.

vOne RJ-45 Ethernet cable
