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:

www.dyndns.org

www.tzo.com

. Note all of

the information provided to you by the DDNS provider.

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

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

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

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.

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:

•

page ¶.)

•

Under

Smart Wi-Fi Tools

, click

Media Prioritization

. The

Media Prioritization

screen opens.

•

Turn on

Prioritization

if it is not already

•

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.

•

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:

•

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.
