you can change any router setting, just as you would normally from your
local network°
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
1.
Log into the browser-based utility (see “How to open the browser-based
utility” on page 22)°
2.
Click the
Administration
tab, then click the
Management
page°
3.
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 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
Wireless > Wireless Security
Status > Wireless Network
Setup > Basic Setup
1.
Make sure that your new router is connected to the Internet°
2.
In the browser-based utility, click the
Wireless
tab
3.
Click the
Basic Wireless Settings
page and take note of the
Network
Name (SSID)
°
4.
Click the
Wireless
tab, then click the
Wireless Security
page and take
note of the
Security Mode
and the passphrase°
5.
Click the
Status
tab, then click the
Wireless Network
page and take note
of the
Channel
°
6.
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)
To use your old router as an access point:
1.
With your computer connected to your old router, log into its browser-
based administration utility°
NOTE
Save your changes after finishing each step below°
2.
Open the setup page for the local network (LAN)°
3.
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°
4.
In the
Subnet Mask
field, enter
255.255.255.0
or, if available, select that
subnet mask from a drop-down list°
5.
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°)
6.
To reconfigure the wireless network on your old router:
a.
Open the wireless network setup page°
b.
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°
c.
Change the security mode to match the security mode on your new
router°
d.
Change the passphrase (sometimes called the pre-shared key) on
your old router to match the passphrase on your new router°
Page 44 / 83

Setting Up: Advanced
Linksys E-Series
e.
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°
7.
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
Do
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:
1.
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°
2.
You are sharing an office building Internet connection, and you want to
control Internet access or the content viewed by your employees°
3.
You already have an existing network and you want to extend the
network’s range or add wireless capabilities to your network°
4.
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 34 or “To
extend your network” on page 36°
To add a router to your existing wireless network:
1.
Insert the Cisco Connect setup CD into a CD/DVD drive on your computer,
then follow the on-screen instructions°
2.
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°
3.
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
1.
Determine the IP address range for your upstream (office or building)
network°
To determine the address range by using a Windows computer:
a.
Connect your computer into your upstream network’s router°
b.
Click
Start
,
Run
, type
CMD
, then click
OK
° The command prompt
window appears°
c.
Type
ipconfig
, then press
Enter
°

Setting Up: Advanced
Linksys E-Series
TIP
Although you can determine your computer’s IP address in many
ways, this method is very fast°
d.
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:
a.
Connect your computer into your upstream network’s router°
b.
From the
Dock
, click
System preferences
, click
Network
, then click
Ethernet
in the window to the left° A network status window appears°
c.
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°
2.
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°
TIPS
An office network often has a wall plate with an Ethernet port that
you can connect to°
If you are doing this in a home environment (without wall ports),
connect an Ethernet network cable between a LAN port on your
upstream router and the
Internet
port on your Linksys router°
3.
Run Cisco Connect on each computer that you want to connect to
the Linksys router° Each computer needs either a wired or wireless
connection to the Linksys router° For more information, see “How to
connect a computer to your network” on page 13°
The computers that are connected to the Linksys router are now on the same
network, and are isolated from the upstream network° However, you will still
have access to the Internet through the upstream router (by way of your Linksys
router)° Because two routers are between your computer and the Internet,
Internet traffic undergoes two network address translations° This is sometimes
referred to as
Double NAT
°
Your computers can also use the built-in capabilities of your Linksys router,
such as parental controls° If you need further control over the type of content
your employees or family access, you can create an account with an Internet
filtering site such as
www.opendns.com
or
www.bsecure.com
° After you
create an account with them, use their DNS in place of your ISP’s DNS°
