How to enable Voice over IP on your

network

For

ALL

Do I need to configure Voice over IP?

VoIP

(Voice over Internet Protocol) is a

technology for using the Internet as an interface for telephone communications°

To use VoIP, you need to get an account with a VoIP service provider° The VoIP

service provider typically provides you with a telephone adapter (TA) that

connects to your network° If you do not use your network to make phone calls,

you don’t need to change the default settings°

The

SIP

(Session Initiation Protocol)

ALG

(Application Layer Gateway) feature

allows SIP packets, used by some VOIP service providers, to traverse (go

through) your router’s firewall°

To configure the router for VoIP:

Administration > Management

Log into the browser-based utility (see “How to open the browser-based

utility” on page 25)°

Click the

Administration

tab, then click the

Management

page°

If your VoIP service uses SIP, select

Enabled

next to

SIP ALG

– OR –

If your VoIP service uses other NAT traversal solutions such as

STUN

(Session Traversal Utilities for NAT),

TURN

(Traversal Using Relay NAT), or

ICE

(Interactive Connectivity Establishment), select

Disabled

(default)°

NOTE

You may need to contact your VoIP service provider to determine

the type of NAT traversal configuration they use°

How to configure UPnP

For

ALL

What is UPnP?

UPnP

(Universal Plug and Play) allows devices connected

to a network to discover each other and automatically create working

configurations° Examples of UPnP-capable devices include web cameras,

online gaming applications, and VoIP devices° UPnP is enabled by default°

To configure UPnP:

Administration > Management

Log into the browser-based utility (see “How to open the browser-based

utility” on page 25)°

How to use a router as an access point

How can I use this new router as an access point?

If you have a large area to

cover with your wireless signal, or if part of your home has weak signals due to

interference, you can use this router to extend the range of your old router’s

wireless network°

For

How can I use my old router as an access point?

If you have a large area to

cover with your wireless signal, or if part of your home has weak signals due to

interference, you can use your old router to extend the range of your wireless

network° This is a complex process, so this procedure assumes that you have

some networking knowledge°

TIP

Check the documentation for your old router° Some brands of

routers include either a switch on the outside of the case or a

software option to convert it to an access point° If either of these

options is available, follow your old router’s instructions to convert

it to an access point°

You need to take note of your new router’s settings, then apply some of those

settings to the old router so it can work as an access point°

To view your new router’s settings:

Wireless > Basic Wireless Settings (non-E4200)

Wireless > Wireless Security (non-E4200)

Wireless > Wireless Settings (E4200)

Status > Wireless Network

Setup > Basic Setup

Make sure that your new router is connected to the Internet°

In the browser-based utility, click the

Wireless

tab

For the E4200, click

Wireless Settings

and take note of the

Network

Name (SSID)

Security Mode

, and

Passphrase

Or, for other Linksys router models:

Click the

Basic Wireless Settings

page and take note of the

Network

Name (SSID)

Click the

Wireless

tab, then click the

Wireless Security

page and

take note of the

Security Mode

and the passphrase°

Click the

Status

tab, then click the

Wireless Network

page and take note

of the

Channel

Click the

Setup

tab, then click the

Basic Setup

page and take note of

the DHCP server’s IP Address range (192°168°1°100 to 192°168°1°149 by

default)

Page 49 / 92

Setting Up: Advanced

Linksys E-Series

To use your old router as an access point:

With your computer connected to your old router, log into its browser-

based administration utility°

NOTE

Save your changes after finishing each step below°

Open the setup page for the local network (LAN)°

In the

Router IP address

field, enter an unused IP address for the LAN

network of your new router°

For example, if your new router has an IP address of 192°168°1°1, you

should choose an IP address on the 192°168°1°0 network° You can choose

any address within the range of 192°168°1°2 to 192°168°1°254° You should

exclude addresses in the range that will be used by the DHCP Server of

your new router (192°168°1°100 to 192°168°1°149)° A safe choice might be

192°168°1°250° Take note of this address, because this will be the address

that you will use to manage your old router in the future°

In the

Subnet Mask

field, enter

255.255.255.0

or, if available, select that

subnet mask from a drop-down list°

Disable the DHCP server on your old router° (Because your old router will

be operating as an access point instead of a router, you don’t want it to

distribute IP addresses° There should be only one active DHCP server on

your network, and that should be your new router°)

To reconfigure the wireless network on your old router:

Open the wireless network setup page°

Change the network name (SSID) to match the name of your new

network° Having the same network name and security settings

enables you to seamlessly roam between your new router and your

old router°

Change the security mode to match the security mode on your new

router°

Change the passphrase (sometimes called the pre-shared key) on

your old router to match the passphrase on your new router°

Change the wireless channel to a non-conflicting channel° Some

manufacturers have an “Auto” function for channel selection that

automatically selects a wireless channel that does not interfere with

other nearby wireless networks° If your old router supports an Auto

function, select that° Otherwise, you may need to manually select the

wireless operating channel on your old router° In the 2°4 GHz wireless

spectrum, there are only three non-overlapping channels: 1, 6, and

11° Pick a channel that does not overlap the operating channel of your

new router° For example, if your new router is operating on channel

11, configure your old router for either channel 1 or channel 6°

Connect an Ethernet network cable to one of the LAN/Ethernet ports on

your old router and an Ethernet port on your new router°

CAUTION

not

connect the cable to the Internet port on your old router° If

you do, you may not be able to set up the router as an access point

on the current network°

How to put your new router behind an

existing router

For

ALL

Why would I put my new router behind an existing router?

There are several

possible scenarios in which you might want to use your new router “behind”

another router:

You might be in an environment that shares the landlord’s Internet

connection with all tenants° In this case, you should put your own router

behind the landlord’s router in order to create your own private network

and to isolate computers on your network from the rest of the building°

You are sharing an office building Internet connection, and you want to

control Internet access or the content viewed by your employees°

You already have an existing network and you want to extend the

network’s range or add wireless capabilities to your network°

You want to separate older, less secure network devices from the rest of

the network°

To add your router to an existing router or gateway

In most cases, you can easily add your router to an existing wireless network by

running Cisco Connect° If you are unable to set up the additional router using

the instructions below, see “To share an Internet connection” on page 38 or “To

extend your network” on page 39°

To add a router to your existing wireless network:

Insert the Cisco Connect setup CD into a CD/DVD drive on your computer,

then follow the on-screen instructions°

When you are told to connect your router’s

Internet

port to the

LAN/

Ethernet

port on your modem, connect your router’s

Internet

port to

the

LAN/Ethernet

port on your existing (upstream) router or gateway°

Follow the on-screen instructions until setup is complete°

To share an Internet connection

NOTE

This is a complex process, so this procedure assumes that you have

some networking knowledge°

To add another router to share an Internet connection:

This topic covers cases one and two above

Determine the IP address range for your upstream (office or building)

network°

To determine the address range by using a Windows computer:

Connect your computer into your upstream network’s router°

Click

Start

Run

, type

CMD

, then click

° The command prompt

window appears°

Type

ipconfig

, then press

Enter

TIP

Although you can determine your computer’s IP address in many

ways, this method is very fast°

Take note of the IP address° In this example, the IP address is

192°168°100°192°

To determine the address range by using a Mac computer:

Connect your computer into your upstream network’s router°

From the

Dock

, click

System preferences

, click

Network

, then click

Ethernet

in the window to the left° A network status window appears°

Take note of the IP address° In this example, the IP address is

192°168°100°139°

Example: The above examples show that upstream IP addresses are on

the 192°168°100°0 network° (The “0” indicates the entire network°) Your

upstream network’s address may be different° The default address of

your new Linksys router is 192°168°1°1° In setting up one router behind

another, you must make sure that the local network on your new router is

different than the network of your upstream router° In the above example,

because the default local network on your Linksys router 192°168°1°0 is

on a different subnet than the office network’s 192°168°100°0, you will be

able to place your Linksys router behind the other router°

Connect an Ethernet network cable to a LAN/Ethernet port on your

upstream network to the yellow

Internet

port on your router°

CAUTION

Connect the upstream network to your router’s yellow

Internet

port,

not

one of the blue Ethernet ports° If you connect to an

Ethernet port, you create IP addressing problems for the office

network°
