HOW TO ACCESS YOUR NETWORK ON THE INTERNET
If you want to remotely access a drive attached to your router or view a web camera
on your home network, you need to be able to easily enter your network’s address
into a web browser.
Working with a DDNS (Dynamic Domain Name System) service provider, your
router’s DDNS feature lets you configure a domain name for your network, which
you can then use to easily find your network on the Internet. If your ISP changes your
network’s IP address (which can happen frequently), the DDNS service providers
detect the address change and continue to route your domain name to that address.
Tip:
Before you configure DDNS on your router, you must sign up for DDNS service
from a DDNS service provider that’s supported by your router.
To set up DDNS:
Sign up for DDNS service at either
www.dyndns.org
or
www.tzo.com
. Note all of
the information provided to you by the DDNS provider.
Log in to Linksys Smart Wi-Fi. (See “How to connect to Linksys Smart Wi-Fi” on
page ¶.)
Under
Router Settings
, click
Security
, then click the
Apps and Gaming
tab. The
DDNS
screen opens.
In the
DDNS Service
drop-down list (the list that has Disabled selected by default),
select your DDNS service provider.
Complete the fields with information provided by your DDNS provider, then
click
OK
.
To access the network from the Internet, enter the domain name provided by
the DDNS service provider.
To access one of your network devices on the Internet, do the following:
•
Configure the router to use port forwarding for the device (see “How to set up
port forwarding for a single port” on page 39). Note the port number used for
the device.
•
Enter the domain name for your network followed by a colon and the port
number. For example, if the domain name registered with your DDNS provider
is
HappyBunny.linksysnet.com
, and your Internet camera has been configured
to use port 1024, you would enter:
HappyBunny.linksysnet.com:1024

HOW TO CLONE A MAC ADDRESS
On any home network, each network device has a unique MAC (Media Access
Control) address. Some ISPs register the MAC address of the device (usually a
router or a computer) connected directly to the modem. If your computer’s MAC
address is registered with your ISP and you do not want to re-register the MAC
address, then you can clone the address (assign the registered MAC address of
your previous device to your new router). If you want to use the MAC address
from an old router that you are replacing with your new router, you should first
determine the MAC address of your old router, then manually enter it into your
new router.
Note:
For many ISPs that provide dynamic IP addresses automatically, the stored
MAC address in the modem is reset each time you reset the modem. If you are
installing this router for the first time, reset your modem before connecting the
router to your modem. To reset your modem, disconnect power for about one
minute, and reconnect power.
To clone a MAC address from your computer, do the following:
•
Log into Linksys Smart Wi-Fi. (See “How to connect to Linksys Smart Wi-Fi” on
page ¶.)
•
Under
Router Settings
, click
Connectivity
. The
Connectivity
page opens.
•
Click the
Internet Settings
tab.
•
Under
MAC Address Clone
, click
Enabled
.
•
Enter the
12-digit MAC address of your old router, then click
OK
.

HOW TO CONNECT TO YOUR CORPORATE OFFICE USING
A VPN
A VPN (Virtual Private Network) uses a public network such as the Internet to
provide secure communications between a remote computer and another network.
Corporations often provide VPN access to their networks to enable employees to
work from remote offices or while traveling. Most corporate VPNs use the Internet
to provide connectivity between remote employees and the corporate network.
For a typical VPN, the corporation installs a VPN gateway on their corporate
network. Employees authorized to work remotely connect to the VPN gateway
through the Internet using VPN software and security methods provided by their
employers. Security and authentication requirements ensure a secure connection
and access by only authorized users.
The default VPN settings in your router have been configured to pass through
(allow) the most common types of VPN protocols. Usually, no changes are needed.
To change your VPN passthrough settings, do the following:
•
Log into Linksys Smart Wi-Fi. (See “How to connect to Linksys Smart Wi-Fi” on
page ¶.)
•
Under
Router Settings
, click
Security
. The
Security
page opens to the
Firewall
tab.
Enable each setting that you want to change:
•
IPSec Passthrough
—
IPSec
(Internet Protocol Security) is a suite of protocols
used to implement secure exchange of packets at the IP layer. The VPN clients on
the local network can establish an IPSec VPN tunnel through the router. This op-
tion is enabled by default.
•
PPTP Passthrough
—
PPTP
(Point-to-Point Tunneling Protocol) allows the PPP
(Point-to-Point Protocol) to be tunneled through an IP network. The VPN clients on
the local network can establish a PPTP VPN tunnel through the router. This option
is enabled by default.
•
L2TP Passthrough
—
L2TP
(Layer 2 Tunneling Protocol) enables point-to-point
sessions using the Internet on the Layer 2 level. The VPN clients on the local net-
work can establish an L2TP VPN tunnel through the router. This option is enabled
by default.
Click
OK
to save your changes.

HOW TO OPTIMIZE YOUR ROUTER FOR GAMING AND VOICE
Your router can prioritize traffic between your network and the Internet. Perfor-
mance for demanding, real-time applications, such as online gaming, VoIP calls,
video streaming, and videoconferencing, can be improved by configuring media
prioritization.
Prioritization settings are applied only to traffic that is uploaded to the Internet.
The router cannot control the quality of the traffic after it reaches the Internet.
Tip:
For more information on optimizing your router for online gaming, see “Port
Forwarding and Port Triggering” on page 40.
To configure media prioritization, do the following:
•
Log in to Linksys Smart Wi-Fi. (See “How to connect to Linksys Smart Wi-Fi” on
page ¶.)
•
Under
Smart Wi-Fi Tools
, click
Media Prioritization
. The
Media Prioritization
screen opens.
•
Turn on
Prioritization
if it is not already
on
.
•
Click and drag high-priority devices from the
Normal Priority
list to the
High Priority
list.
•
To prioritize an application or game, select the name in the drop-down list, then
click and drag the icon next to the name to the
High Priority
list.
•
If the application name isn’t listed, click
Edit
and add the name.
Tip:
If you want to add a new application or game, you need to know its port and
protocol information (see the application or game’s documentation for help).
•
Click
Settings
. The
Settings
screen opens.
•
Set the maximum Downstream Bandwidth. If you set the bandwidth lower than the
actual bandwidth of your router, performance may be limited.
•
Set the maximum Upstream Bandwidth.
•
To help manage traffic priority with devices that support WMM, turn on WMM
Support.
•
To have the router resend data if an error occurs, turn off No Acknowledgement.
•
Click
OK
.

Tip:
WMM (Wi-Fi MultiMedia) Support is a wireless feature based on the IEEE
802.11e standard. WMM improves quality for audio, video, and voice
applications by prioritizing wireless traffic. This feature requires that the
wireless client devices in your network also support WMM.
Caution:
If you specify a maximum bandwidth that is too high, the router cannot apply
priorities correctly, and prioritization problems may result.
HOW TO ENABLE VOICE OVER IP ON YOUR NETWORK
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 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 Application Layer Gateway SIP (Session Initiation Protocol) allows SIP pack-
ets, used by some VOIP service providers, to get through your router’s firewall.
To configure the router for VoIP, do the following:
•
Log in to Linksys Smart Wi-Fi. (See “How to connect to Linksys Smart Wi-Fi” on
page ¶.)
•
Under
Router Settings
, click
Connectivity,
then click the
Administration
tab.
If your VoIP service uses SIP, select the SIP checkbox under
Application Layer
Gateway
.
- 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), deselect the SIP checkbox.
Note:
You may need to contact your VoIP service provider to determine the type of
NAT traversal configuration they use.
