How to set up DHCP reservation
Why would I use it?
DHCP reservation
allows you to assign a unique, fixed IP
address to a specific device on your network° Assigning a fixed IP address is
a good way to manage devices such as print servers, web cameras, network
printers, and game consoles° A fixed IP address is also recommended if you
want to use port forwarding for devices that need to receive inbound traffic
from the Internet (“How to set up port forwarding” on page 57)°

How to find your network on the Internet
For
ALL
Why would I need to find my network on the Internet?
If you want to
remotely access a USB drive attached to your router or view a web camera, you
need to find your network on the Internet°
Working with several DDNS service providers, 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, 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:
Setup > DDNS
1.
Sign up for DDNS service at either
www.dyndns.org
or
www.tzo.com
°
2.
Log into the browser-based utility (see “How to open the browser-based
utility” on page 25)°
3.
Click the
Setup
tab, then click the
DDNS
page°
4.
In the
DDNS Service
drop-down list, click your DDNS service provider°
The examples below are based on TZO°com° The settings used by
DynDNS°org are slightly different°
Page 43 / 92

Setting Up: Advanced
Linksys E-Series
5.
Complete the fields with information provided by your DDNS provider,
then click
Save Settings
° The
Status
field tells you what actions have
been taken°
In this example, the domain name registered with TZO°com is
BronzeEagle953.linksysnet.com
° If an Internet camera had been configured
(see “How to set up port forwarding for a single port” on page 57), you
could access the camera by typing the domain name into the address bar
of your web browser followed by the port number used for the device°
For example, if the camera in the above example used port 1024, the URL
would be:
BronzeEagle953.linksysnet.com:1024
How to clone a MAC address
For
ALL
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, then reconnect
power°
To clone a MAC address from your computer:
Setup > MAC Address Clone
1.
Log into the browser-based utility (see “How to open the browser-based
utility” on page 25)°
2.
Click the
Setup
tab, then click the
MAC Address Clone
page°
3.
Click
Enabled
°
4.
Click either
Clone My PC’s MAC
or enter the 12-digit MAC address of
your old router°

How to connect to your corporate office
using a VPN
For
ALL
What is a VPN, and do I need to change my router settings?
A
VPN
(Virtual
Private Network) is a network that 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° Robust security and authentication schemes 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, so usually no changes are
needed°
To change your VPN passthrough settings:
Security > VPN Passthrough
1.
Log into the browser-based utility (see “How to open the browser-based
utility” on page 25)°
2.
Click the
Security
tab, then click the
VPN Passthrough
page°
3.
Select each setting that you want to change°
TIP
For brief descriptions of the VPN passthrough field settings, click
Help
in the right side of the screen° More complete descriptions are
provided below°
•
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 option 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 network can establish an L2TP VPN tunnel through
the router° This option is enabled by default°

How to optimize your router for gaming
and voice
For
ALL
How does my router prioritize traffic to the Internet?
Your router has
QoS
(Quality of Service) settings that can prioritize traffic from your network out to
the Internet° Performance for demanding, real-time applications, such as online
gaming, VoIP calls, video streaming, and videoconferencing, can be improved
by configuring Internet access priorities°
QoS is 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 57°
Page 45 / 92

°
TIP
WMM
(Wi-Fi MultiMedia) Support is a wireless QoS 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°

°
6.
In the
Category
drop-down list, select the type of item you want to set a
priority for° A list of installed items fitting that description appears°
TIP
Do not set all priorities to
High
, because all items will have the
same priority, and it would be easier to disable Internet Access
Priority for the same result°
•
Applications
and
Online Games
—Let you assign a priority for an
application or online game°
a)
Select the application or online game that you want to add from
the drop-down list, then select the priority°
b)

and
Voice Device
—Let you prioritize network traffic
based on the device that is accessing the network° For example, if you
want your gaming console to have higher priority than your computer
for accessing the Internet, you can assign a higher priority to your
game console using its MAC address° We recommend giving any voice
devices a high priority°
a)
Select
MAC Address
or
Voice Device
from the drop-down list,
then enter the name of the device you want to add°
b)
Enter the device’s 12-digit MAC address, then select the priority°
c)
Click
Apply
, then click
Save Settings
°
TIP
You can often find a device’s 12-digit MAC address on the bottom
of the device° Or, if the device is connected to your network and
turned on, you can click the
Administration
tab in the router’s
browser-based utility, click the
Local Network
page, then click
DHCP Client Table
