Changing IPv6 firewall settings
On some router models, the IPv6 firewall lets you customize IPv6 port services
for applications. When users send these types of requests to your network via
the Internet, the router will allow those requests to the appropriate computers.
NOTE
To use your router’s IPv6 Internet connectino settings, IPv6 service
from your ISP (Internet service provider) is required. For more
information on this service, ask your ISP.
To set IPv6 firewall settings:
1.
Log into Cisco Connect Cloud. (See “How to configure your router” on
page 14.
2.
Under
Router Settings
, click
Security
. The
Security
page opens to the
Firewall
tab.
3.
Click Add IPv6 Firewall Setting. You can now change the following fields:
•
Description
—Enter a description of the application.
•
Protocol
—Select
TCP
,
UDP
, or

(default).
•
IPv6 Address
—Enter the IPv6 address of the computer that should
receive the traffic.
•
Allow
—Select the range of port(s) used by incoming traffic.

How to set up the DHCP server on your
router
Your router can be used as a
DHCP
(Dynamic Host Configuration Protocol)
server to automatically assign an IP address to each computer or device on
your network. The DHCP server is enabled by default. If you already have a
DHCP server on your network, or if you do not want to use your router as a
DHCP server, you should disable this setting.
To configure your router’s DHCP server settings:
1.
Log into Cisco Connect Cloud. (See “How to configure your router” on
page 14.
2.
Under
Router Settings
, click
Connectivity
.

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 51).
To configure DHCP reservation:
1.
Log into Cisco Connect Cloud. (See “How to configure your router” on
page 14.
2.
Under
Router Settings
, click
Connectivity
.
3.
Click the
Local Network
tab, then click
DHCP Reservations
. The
DHCP
Reservations
list opens, which lists attached network devices and current
DHCP reservations.
4.
Click the
Select
checkbox next to the device you want to reserve, then
click
Add DHCP Reservation

How to access your network on the
Internet
Why would I need to find my 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 several DDNS (Dynamic Domain Name System) 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 (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:
1.
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.
2.
Log into Cisco Connect Cloud. (See “How to configure your router” on
page 14.
3.
Under
Router Settings
, click
Security,
then click the
Apps and Gaming
tab. The DDNS screen opens.
4.
In the DDNS Service drop-down list (the list that has
Disabled
selected
by default), select your DDNS service provider.
5.
Complete the fields with information provided by your DDNS provider,
then click
OK
.
6.
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:
a.
Configure the router to use port forwarding for the device (see “How
to set up port forwarding for a single port” on page 51). Note the port
number used for the device.
b.
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, then reconnect
power.
To clone a MAC address from your computer:
1.
Log into Cisco Connect Cloud. (See “How to configure your router” on
page 14.
2.
Under
Router Settings
, click
Connectivity
. The
Connectivity
page opens.
3.
Click the
Internet Settings
tab.
4.
Under
MAC Address Clone
, click
Enabled
.
5.
Enter the 12-digit MAC address of your old router, then click
OK
.
How to connect to your corporate office
using a VPN
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:
1.
Log into Cisco Connect Cloud. (See “How to configure your router” on
page 14.
2.
Under
Router Settings
, click
Security
. The
Security
page opens to the
Firewall
tab.

•
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
How does my router prioritize traffic to the Internet?
Your router can
prioritize traffic between your network and the Internet. Performance 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 51.
To configure media prioritization:
1.
Log into Cisco Connect Cloud. (See “How to configure your router” on
page 14.
2.
Under
Apps
, click
Media Prioritization
. The
Media Prioritization
screen
opens.
3.
Turn on
Prioritization
if it is not already on.
4.
Click and drag high-priority devices from the
Normal Priority
list to the
High Priority
list.
