Setting Client IP Filters
The Router can be configured to restrict access to the Internet, email, or other
network services. 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 to which you wish to restrict access in the IP fields. Next,
enter “80” in both the port fields. Select “Both”. Select “Block”. You can also
select “Always” to block access all of the time. Select the day to start on top, the
time to start on top, the day to end on the bottom, and the time to stop on the
bottom. Select “Enable”. 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”
(1)
.
Next, select the MAC address you would like to add to the list from the drop-
down menu of currently connected computers, click “Copy to”, and select the slot
to which to add the MAC address
(2)
. You can also manually enter the MAC
address in the space provided
(3)
. Click “Apply Changes” to save the settings.
You can have a MAC-address-filtering list of up to 32 computers.
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.
