Introduction
This Chapter provides an overview of the Internet Broadband Router's
features and capabilities.
Congratulations on the purchase of your new Internet Broadband Router- XRT-101A. The
Internet Broadband Router will allow multiple LAN users to share an Internet user account, via
a DSL or Cable modem. Once the Internet Broadband Router is installed and configured, the
Internet is just a click away.

Internet Broadband Router Features
The Internet Broadband Router incorporates many advanced features, carefully designed to
provide sophisticated functions while being easy to use.
Internet Access Features
•Shared Internet Access. All users on the LAN or WLAN can access the Internet
through the Internet Broadband Router, using only a single external IP Address. The local
(invalid) IP Addresses are hidden from external sources. This process is called NAT
(Network Address Translation).
•DSL & Cable Modem Support. The Internet Broadband Router has a 10BaseT
Ethernet port for connecting a DSL or Cable Modem. All popular DSL and Cable Modems
are supported.
•PPPoE and PPTP Support. The Internet (WAN port) connection supports PPPoE
(PPP over Ethernet) and PPTP (Peer-to-Peer Tunneling Protocol), as well as "Direct
Connection" type services.
•Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the Internet
Broadband Router supports both Dynamic IP Address (IP Address is allocated on
connection) and Fixed IP Address.

Advanced Internet Functions
•Conferencing & Telephony Applications. Internet Telephony and Conferencing
applications, which are often difficult to use when behind a Firewall, are supported.
•Special Internet Applications. Applications which use non-standard connections or
port numbers are normally blocked by the Firewall. The ability to define and allow such
applications is provided, to enable such applications to be used normally.
•Virtual Servers. This feature allows Internet users to access Internet servers on your
LAN. The required setup is quick and easy.
•DMZ. One (1) PC on your local LAN can be configured to allow unrestricted 2-way
communication with Servers or individual users on the Internet. This provides the ability to
run programs which are incompatible with Firewalls.
•URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users.
•Internet Access Log. See which Internet connections have been made.
•VPN Support. VPN (Virtual Private Networking) connections using PPTP and IPSec are
transparently supported - no configuration is required.
LAN Features
•Dual Ethernet ports. The Internet Broadband Router has 2 Ethernet ports. One (the
LAN port) is used to connect to your local LAN. The other (the WAN port) is connected to
your DSL or Cable modem.
•DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP
address to PCs and other devices upon request. The Internet Broadband Router can act as a
DHCP Server for devices on your local LAN and WLAN.
•Multi Segment LAN Support. LANs containing one or more segments are supported,
via the Internet Broadband Router's RIP (Routing Information Protocol) support and built-
in static routing table.
Configuration & Management
•Easy Setup. Use your WEB browser from anywhere on the LAN for configuration.
•Remote Management. The Internet Broadband Router can be managed from any PC on
your LAN. And, if the Internet connection exists, it can also (optionally) be configured via
the Internet.
•UPnP Support. UPnP (Universal Plug and Play) allows automatic discovery and
configuration of the Internet Broadband Router. UPnP is by supported by Windows ME,
XP, or later.

Introduction

Security Features
•Password - protected Configuration. Optional password protection is provided to
prevent unauthorized users from modifying the configuration data and settings.
•NAT Protection. An intrinsic side effect of NAT (Network Address Translation)
technology is that by allowing all LAN users to share a single IP address, the location and
even the existence of each PC is hidden. From the external viewpoint, there is no network,
only a single device - the Internet Broadband Router.
•Stateful Inspection Firewall. All incoming data packets are monitored and all
incoming server requests are filtered, thus protecting your network from malicious attacks
from external sources.
•Protection against DoS attacks. DoS (Denial of Service) attacks can flood your
Internet connection with invalid packets and connection requests, using so much bandwidth
and so many resources that Internet access becomes unavailable. The Internet Broadband
Router incorporates protection against DoS attacks.
Package Contents
The following items should be included:
•The Internet Broadband Router Unit

DHCP
What DHCP Does
A DHCP (Dynamic Host Configuration Protocol) server allocates a valid IP address to a
DHCP client (PC or device) upon request.
•The client request is made when the client device starts up (boots).
•The DHCP Server provides the Gateway and DNS addresses to the client, as well as
allocating an IP Address.
•The Internet Broadband Router can act as a DHCP server.
•Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP client.
This is the default Windows setting for the TCP/IP network protocol. However, Windows
uses the term Obtain an IP Address automatically instead of "DHCP Client".
•You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your
LAN does not have other Routers, this means there must only be one (1) DHCP Server on
your LAN.)
Using the Internet Broadband Router's DHCP Server
This is the default setting. The DHCP Server settings are on the LAN screen. On this screen,
you can:
•Enable or Disable the Internet Broadband Router's DHCP Server function.
•Set the range of IP Addresses allocated to PCs by the DHCP Server function.
You can assign Fixed IP Addresses to some devices
while using DHCP, provided that the Fixed IP Addresses
are NOT within the range used by the DHCP Server.
Using another DHCP Server
You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP
Server, rather than the Internet Broadband Router's, the following procedure is required.
1. Disable the DHCP Server feature in the Internet Broadband Router. This setting is on the
LAN screen.
2. Configure the DHCP Server to provide the Internet Broadband Router's IP Address as the
Default Gateway.
To Configure your PCs to use DHCP
This is the default setting for TCP/IP under Windows 95/98/ME. See Chapter 4 - Client
Configuration for the procedure to check these settings.
