INTRODUCTION

Thank you for purchasing the XRouter MIH-120 Internet Sharing

Hub. The XRouter functions as an easy-to-use communication device
that allows you to connect a local area network (LAN) to the Internet
affordably. With the XRouter you can get as many as 252 Macintosh or
PC users online simultaneously through just one cable line or DSL,
and one ISP account. The XRouter installs quickly and easily, and best
of all, it’s a breeze to use.

Sharing Internet Access

The XRouter provides high-speed Internet access to multiple users

by splitting the bandwidth from a cable line or from DSL (Digital
Subscriber Line) into tiny portions and then routing these bandwidth
“slices” to almost any number of Internet users. The fewer the number
of users online at any one time, the faster the service each individual
receives. Internet users on different nodes are not limited to looking at
the same Web pages. Each node is functionally independent from the
other nodes connected to the XRouter.

Modems Supported

The XRouter supports cable modems and DSL modems. The

XRouter has one WAN (Wide Area Network) port for connecting the
unit to either a cable modem or a DSL modem. Either technology
should provide more than enough bandwidth to accommodate the
needs of even large groups of Internet users.

Built-in DHCP Server

The XRouter’s built-in DHCP Server dramatically reduces the

configuration and maintenance effort by allowing you to automatically
configure the TCP/IP setting of computers over a local area network.

Introduction

4-Port Ethernet Hub Inside

In addition to providing Internet sharing capability, the XRouter

also functions as an Ethernet hub, offering four 10BASE-T, RJ-45 ports
that allow you to connect a series of computers to form a small LAN.

Easy Configuration

The XRouter can be configured through a Web browser, and fea-

tures Web-based management for a simple, intuitive set up.

Virtual Server

Internet users can set up an in-house Web server, such as WWW

or FTP, through the XRouter’s Virtual Server mapping function. The
Virtual Server allows you to select a particular computer in your
network to respond to outside Internet requests.

Security

The XRouter provides firewall-like security through NAT (Network

Address Translation) to prevent unauthorized Internet users from
accessing internal files. It can also filter out Internet requests from
certain nodes on a local network for administrative purposes.

NAT (Network Address Translation)

The XRouter features NAT (Network Address Translation) as a

means of translating private IP addresses into a global IP address that
is, in turn, registered to the Internet. NAT essentially masks local IP
addresses to the outside world, allowing a group of Internet users to
share a single ISP account (which means you don’t have to buy sepa­rate accounts for each user).
