Chapter 1: Introduction

Welcome

Thank you for choosing the Broadband Router with 2 Phone Ports. This Router will allow your computers to share
a high-speed Internet connection as well as resources, including files and printers. And after you have set up
your Internet phone service, you will be able to make phone or fax calls using your Internet connection.

How does the Router do all of this? By connecting your computers and peripherals, including phones or fax
machines, to the Router and connecting the Router to your cable or DSL modem, then the Router can direct and
control communications for your network.

But what does all of this mean?

Networks are useful tools for sharing Internet access and computer resources. Multiple computers can share
Internet access, so you don’t need more than one high-speed Internet connection. With Internet phone service,
your Internet access can now be shared by your phones or fax machines as well. You will be able to make phone
calls using the account you set up with your Internet phone service, even while you’re surfing the Internet. Plus,
you can access one printer from different computers and access data located on another computer’s hard drive.
Networks are even used for playing multiplayer video games. So, networks not only are useful in homes and
offices, but also can
be fun.

PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is
why the network is called “wired”.

Chapter 1: Introduction
Welcome

lan (local area network): the computers
and networking products that make up
the network in your home or office.

ethernet: an IEEE standard network
protocol that specifies how data is placed
on and retrieved from a common
transmission medium.

Chapter 2: Networking Basics

An Introduction to Local Area Networks

Simply put, a router is a network device that connects two networks together.

The Router connects your local area network (LAN), or the group of PCs in your home or office, to the Internet.
The Router processes and regulates the data that travels between these two networks.

Broadband Router with 2 Phone Ports

The Router’s Network Address Translation (NAT) technology protects your network of PCs so users on the
Internet cannot “see” your PCs. This is how your LAN remains private. The Router protects your network by
inspecting the first packet coming in through the Internet port before delivery to the final destination on one of
the Ethernet ports. The Router inspects Internet port services like the web server, ftp server, or other Internet
applications, and, if allowed, it will forward the packet to the appropriate PC on the LAN side.

The Use of IP Addresses

IP stands for Internet Protocol. Every device in an IP-based network, including PCs, print servers, and routers,
requires an IP address to identify its location, or address, on the network. This applies to both the Internet and
LAN connections.

There are two ways of assigning IP addresses to your network devices.

A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a
static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will
always have that same IP address until you change it. Static IP addresses are commonly used with network
devices such as server PCs or print servers.

Chapter 2: Networking Basics
An Introduction to Local Area Networks

nat (network address translation): NAT
technology translates IP addresses of a
local area network to a different IP
address for the Internet.

static ip address: a fixed address
assigned to a computer or device that is
connected to a network.

5

Broadband Router with 2 Phone Ports

If you use the Router to share your cable or DSL Internet connection, contact your ISP to find out if they have
assigned a static IP address to your account. If so, you will need that static IP address when configuring the
Router. You can get the information from your ISP.

A dynamic IP address is automatically assigned to a device on the network. These IP addresses are called
dynamic because they are only temporarily assigned to the PC or other device. After a certain time period, they
expire and may change. If a PC logs onto the network (or the Internet) and its dynamic IP address has expired,
the DHCP server will assign it a new dynamic IP address.

A DHCP server can either be a designated PC on the network or another network device, such as the Router. By
default, the Router’s Internet Connection Type is Obtain an IP automatically (DHCP).

The PC or network device obtaining an IP address is called the DHCP client. DHCP frees you from having to
assign IP addresses manually every time a new user is added to your network.

For DSL users, many ISPs may require you to log on with a user name and password to gain access to the
Internet. This is a dedicated, high-speed connection type called Point to Point Protocol over Ethernet (PPPoE).
PPPoE is similar to a dial-up connection, but PPPoE does not dial a phone number when establishing a
connection. It also will provide the Router with a dynamic IP address to establish a connection to the Internet.

By default, a DHCP server (on the LAN side) is enabled on the Router. If you already have a DHCP server running
on your network, you MUST disable one of the two DHCP servers. If you run more than one DHCP server on your
network, you will experience network errors, such as conflicting IP addresses. To disable DHCP on the Router,
see the Basic Setup section in “Chapter 5: Configuring the Router.”

dynamic ip address: a temporary IP
address assigned by a DHCP server.

dhcp (dynamic host configuration
protocol): a protocol that lets one device
on a local network, known as a DHCP
server, assign temporary IP addresses to
the other network devices, typically
computers.

MTU. The MTU (Maximum Transmission Unit) setting specifies the largest packet size permitted for network
transmission. Select Enable and enter the value desired. It is recommended that you leave this value in the 1200
to 1500 range. For most DSL users, it is recommended to use the value 1492. By default, MTU is set at 1500
when disabled.

Network Setup

The Network Setup section allows you to change the Router’s local network settings.

Router IP

The values for the Router’s Local IP Address and Subnet Mask are shown here. In most cases, keeping the

Local IP Address. The default value is 192.168.15.1.

Subnet Mask. The default value is 255.255.255.0.

Network Address Server Settings (DHCP)

These settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function.
The Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address
to each computer on your network. Unless you already have one, it is highly recommended that you leave the
Router enabled as a DHCP server.

Local DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, set
the Router’s DHCP option to Disable. If you disable DHCP, remember to assign a static IP address to the Router.

Start IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the
default IP address for the Router is 192.168.15.1, the Start IP Address must be 192.168.15. 2 or greater, but
smaller than 192.168.15.254. The default Start IP Address is 192.168.15.100.

Number of Address (Optional). Enter the maximum number of PCs that you want the DHCP server to assign IP
addresses to. This number cannot be greater than 253. The default is 50.

DHCP Address Range. The range of DHCP addresses is displayed here.

Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the

Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased”
this dynamic IP address. After the dynamic IP address has expired, the user will be automatically assigned a new
dynamic IP address. The default is 0 minutes, which means one day.
