XRT-711A Features
The 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 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 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
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
•7-Port Switching Hub. The Broadband Router incorporates a 7-port 10/100BaseT
switching hub, making it easy to create or extend your LAN.
•DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP
address to PCs and other devices upon request. The 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 Broadband Router's RIP (Routing Information Protocol) support and built-in static
routing table.
•Network Printer. The printer attached to the Broadband Router becomes a "Network
Printer", available to all Windows and Linux (Unix) clients on your LAN.
Configuration & Management
•Easy Setup. Use your WEB browser from anywhere on the LAN for configuration.
•Remote Management. The 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 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 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 Broadband Router
incorporates protection against DoS attacks.
Package Contents

configure it, using your Web Browser. Your Browser must support JavaScript. The
configuration program has been tested on the following browsers:
•Netscape V4.08 or later
•Internet Explorer V4 or later
Preparation
Before attempting to configure the Broadband Router, please ensure that:
•Your PC can establish a physical connection to the Broadband Router. The PC and the
Broadband Router must be directly connected (using the Hub ports on the Broadband
Router) or on the same LAN segment.
•The Broadband Router must be installed and powered ON.
•If the Broadband Router's default IP Address (192.168.0.1) is already used by another
device, the other device must be turned OFF until the Broadband Router is allocated a new
IP Address during configuration.
Connecting to the Broadband Router
Using UPnP
If your Windows system supports UPnP, an icon for the Broadband Router will appear in the
system tray, notifying you that a new network device has been found, and offering to create a
new desktop shortcut to the newly-discovered device.

segment to which the Broadband Router is attached (the same value as
the PCs on that LAN segment).
DHCP Server •If Enabled, the Broadband Router will allocate IP Addresses to
PCs (DHCP clients) on your LAN when they start up. The default
(and recommended) value is Enabled.
•If you are already using a DHCP Server, this setting must be
Disabled, and the existing DHCP server must be re-configured to
treat the Broadband Router as the Gateway. See the following
section for further details.
•The Start IP Address and Finish IP Address fields set the values
used by the DHCP server when allocating IP Addresses to DHCP
clients. This range also determines the number of DHCP clients
supported.

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 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 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 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 Broadband Router's, the following procedure is required.
1. Disable the DHCP Server feature in the Broadband Router. This setting is on the LAN
screen.
2. Configure the DHCP Server to provide the 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.
