Chapter 1 Overview of the system
1.1 Introduction
The LW2100AP delivers the freedom to configure the network without wire and functions as an
IEEE 802.3 Ethernet-based Residential Gateway. It provides 10/100 Dual Speed Ethernet port
for a DSL Modem, Cable Modem, or other Broadband access device and one 10M Ethernet port
for connection to a home or small office network.
LW2100AP can forward all packet between local and Internet such as ICMP, FTP, Real Audio,
Quake, H.225 packet. Also support virtual server(DMZ server) that forward incoming packet to
specified LAN host system.
LW2100AP supports DHCP server to setup network configuration for each local PC dynamically.
LW2100AP use graphical user interface(web-browser) to setup, check system status, change
password, and upgrade system image.
The LW2100AP has one local 10Mbps Ethernet port and one 10/100Mbps Dual Speed Ethernet
global port. The local port can be connected directly to a single computer or it can be
connected to an Ethernet hub or switch to provide Internet Sharing and Firewall protection to a
local area network. The global port can be connected to any Cable, DSL, or Broadband modem
with an Ethernet port.
Unlike proxy server or NAT software that requires the software server to remain visible on the
Internet, no local computers are directly and externally visible when using the LW2100AP.
Integrated DHCP services allow up to 63 users to get their IP address automatically on boot up
from the LW2100AP.
The LW2100AP can be set to allow separate FTP, Web, and Multiplayer game servers to share
the same Internet-visible IP address while still protecting the servers and local users from
hackers.

1.3. Network Setting for PC
Client machines(PC) require no software, simply set them to accept a dynamically assigned IP
address and reboot. Each time they are powered up the LW2100AP will recognize them and
set their IP address to instantly connect them to the LAN.
If you want to use an assigned (static) IP address, you can select “Specify an IP address” in
“TCP/IP Properties” window.
 How to Set DHCP Client (in Win98)
a. Select Control Panel(Network('TCP/IP' (TCP/IP is only for LGE card). Then the
“TCP/IP Properties” window will be brought to the screen. Click the “IP

Chapter 2 WEB Server Manual
2.1 Execution of WEB Server and AP connection to WEB Server
This chapter explains how to connect the LW2100AP to the Internet using Web-based
management tool.
The first step is to execute the Internet browser directly and to enter the IP address of an AP to
connect. At this time, it is possible only if the IP address of an AP to connect is already known.
The default IP address of an AP in factory shipment is 10.0.0.1
The AP connection to WEB Server is available for a PC that can execute the Internet browser
and connect with the Internet. If the AP connection to WEB Server operates normally, a window
indicating to input the password of connected AP is open.
The default value of the username and the password is “root”, “lw2100ap” respectively.
If the password is correctly entered, the initial Home screen displays as follows.
At this time, the access to WEB Server is available.
* The Web-based management system is fully compatible with Microsoft Internet Explorer
versions 4.0 or later and Netscape Communicator versions 4.0 or later. Earlier versions of these
browsers cannot use all features of the management system.
