Setting Client IP Filters
The Router can be configured to restrict access to the Internet, email, or
other network services at specific days and times. Restriction can be set for
a single computer, a range of computers, or multiple computers.
To restrict Internet access to a single computer, for example, enter the IP
address of the computer you wish to restrict access to in the IP fields (1).
Next, enter “80” in both the port fields (2). Select “Both” (3). Select “Block”
(4). You can also select “Always” to block access all of the time. Select the
day to start on top (5), the time to start on top (6), the day to end on the
bottom (7), and the time to stop (8) on the bottom. Select “Enable” (9). Click
“Apply Changes”. The computer at the IP address you specified will now be
blocked from Internet access at the times you specified. Note: Be sure you
have selected the correct time zone under “Utilities> System Settings>
Time Zone”.

Setting MAC Address Filtering
The MAC address filter is a powerful security feature that allows you
to specify which computers are allowed on the network. Any computer
attempting to access the network that is not specified in the filter list
will be denied access. When you enable this feature, you must enter
the MAC address of each client (computer) on your network to allow
network access to each.

To enable this feature, select “MAC Address Filtering” and click
“Enable MAC Address Filtering” (1). Next, enter the MAC address of
each computer on your network by clicking in the space provided (2)
and entering the MAC address of the computer you want to add to the
list. Click “Add” (3), then “Apply Changes” to save the settings. You
can have a MAC-address-filtering list of up to 32 computers.
Note: You will not be able to delete the MAC address of the computer
you are using to access the Router’s administrative functions (the
computer you are using now).

Enabling the Demilitarized Zone (DMZ)
The DMZ feature allows you to specify one computer on your network to
be placed outside of the firewall. This may be necessary if the firewall
is causing problems with an application such as a game or video
conferencing application. Use this feature on a temporary basis. The
computer in the DMZ is NOT protected from hacker attacks.
Note: If your ISP subscription provides you with additional public (WAN)
IP addresses, additional computers can be placed outside the firewall
provided each computer uses a different public (WAN) IP.
To put a computer in the DMZ, enter the last digits of its IP address in
the IP field and select “Enable”. Click “Apply Changes” for the change to
take effect.

Using Dynamic DNS
The Dynamic DNSSM service allows you to alias a dynamic IP address
to a static host name in any of the many domains DynDNS.org offers,
allowing your network computers to be more easily accessed from
various locations on the Internet. DynDNS.org provides this service,
for up to five host names, free to the Internet community.
The Dynamic DNS service is ideal for a home website, file server, or to
make it easy to access your home PC and stored files while you’re at
work. Using the service can ensure that your host name always points
to your IP address, no matter how often your ISP changes it. When
your IP address changes, your friends and associates can always
locate you by visiting yourname.dyndns.org instead!
To register free for your Dynamic DNS host name, please visit http://
www.dyndns.org.

Setting up the Router’s Dynamic DNS Update Client
You must register with DynDNS.org’s free update service before
using this feature. Once you have your registration, follow the
directions below.
1. Select DynDNS as the “DDNS Service” (1).
2. Enter your DynDNS.org user name in the “User Name” field (2).
3. Enter your DynDNS.org password in the “Password” field (3).
4. Enter the DynDNS.org domain name you set up with DynDNS.org in the
“Domain Name” field (4).
5. Click “Update Dynamic DNS” (5) to update your IP address.
Whenever your IP address assigned by your ISP changes, the Router will
automatically update DynDNS.org’s servers with your new IP address. You
can also do this manually by clicking the “Update Dynamic DNS” button (5).

WAN Ping Blocking
Computer hackers use what is known as “pinging” to find potential
victims on the Internet. By pinging a specific IP address and receiving
a response from the IP address, a hacker can determine that
something of interest might be there. The Router can be set up so it
will not respond to an ICMP ping from the outside. This heightens the
level of security of your Router.
To turn off the ping response, select “Block ICMP Ping” (1) and click
“Apply Changes”. The Router will not respond to an ICMP ping.

Changing System Settings
The “System Settings” page is where you can enter a new administrator
password, set the time zone, enable remote management, and turn on and
off the UPnP function of the Router.
Setting or Changing the Administrator Password
The Router ships with NO password entered. If you wish to add a
password for greater security, you can set a password here. Write down
your password and keep it in a safe place, as you will need it if you need to log
into the Router in the future. It is also recommended that you set a password if
you plan to use the remote management feature of your Router.
Changing the Login Time-Out Setting
The login time-out option allows you to set the period of time that you can
be logged into the Router’s Web-Based Advanced User Interface. The timer
starts when there has been no activity. For example, you have made some
changes in the Web-Based Advanced User Interface, then left your computer
alone without clicking “Logout”. Assuming the time-out is set to 10 minutes,
then 10 minutes after you leave, the login session will expire. You will have
to log into the Router again to make any more changes. The login time-out
option is for security purposes and the default is set to 10 minutes.
Note: Only one computer can be logged into the Router’s Web-Based
Advanced User Interface at one time.

Setting the Time and Time Zone
The Router keeps time by connecting to a Simple Network Time
Protocol (SNTP) server. This allows the Router to synchronize the
system clock to the global Internet. The synchronized clock in the
Router is used to record the security log and control client filtering.
Select the time zone that you reside in. If you reside in an area that
observes daylight saving, then place a check mark in the box next
to “Automatically Adjust Daylight Saving”. The system clock may not
update immediately. Allow at least 15 minutes for the Router to contact
the time servers on the Internet and get a response. You cannot set the
clock yourself.
Enabling Remote Management
Before you enable this advanced feature of your Belkin Router, MAKE
SURE YOU HAVE SET THE ADMINISTRATOR PASSWORD. Remote
management allows you to make changes to your Router’s settings
from anywhere on the Internet. There are two methods of remotely
managing the Router. The first is to allow access to the Router from
anywhere on the Internet by selecting “Any IP address can remotely
manage the Router”. By typing in your WAN IP address from any
computer on the Internet, you will be presented with a login screen
where you need to type in the password of your Router. The second
method is to allow a specific IP address only to remotely manage the
Router. This is more secure, but less convenient. To use this method,
enter the IP address you know you will be accessing the Router from
in the space provided and select “Only this IP address can remotely
manage the Router”. Before you enable this function, it is STRONGLY
RECOMMENDED that you set your administrator password. Leaving the
password empty will potentially open your Router to intrusion.

Enabling/Disabling UPnP
UPnP (Universal Plug-and-Play) is yet another advanced feature offered
by your Belkin Router. It is a technology that offers seamless operation of
voice messaging, video messaging, games, and other applications that
are UPnP-compliant. Some applications require the Router’s firewall to
be configured in a specific way to operate properly. This usually requires
opening TCP and UDP ports. An application that is UPnP-compliant has
the ability to communicate with the Router, basically “telling” the Router
which way it needs the firewall configured. The Router ships with the
UPnP feature enabled. If you If you want to disable the UPnP feature,
simply select “Disable” in the “UPnP Enabling” section of the “Utilities”
page. Click “Apply Changes” to save the change.
