USING THE WEB-BASED ADVANCED USER INTERFACE
Setting MAC Address Control
The MAC address filter is a powerful security feature that allows you to specify which computers are allowed on the wireless network�
Note:
This list
applies only to wireless computers� This list can be configured so any computer attempting to access the wireless 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) to which you want to allow
network access� The “Block” feature lets you turn on and off access to the network easily for any computer without having to add and remove the
computer’s MAC address from the list�
Setting up an Allow Access List
1�
Select the “Allow” radio button
(1)
to begin setting up a list of
computers allowed to connect to the wireless network�

the wireless network, then click “<<Add”

USING THE WEB-BASED ADVANCED USER INTERFACE
Configuring the Firewall
Your Router is equipped with a firewall that will protect your network
from a wide array of common hacker attacks including:
•
IP Spoofing
•
Land Attack Ping of Death (PoD)
•
Denial of Service (DoS)
•
IP with zero length
•
Smurf Attack
•
TCP Null Scan
•
SYN flood
•
UDP flooding
•
Tear Drop Attack
•
ICMP defect
•
RIP defect
•
Fragment flooding
The firewall also masks common ports that are frequently used to
attack networks� These ports appear to be “stealth” meaning that for
all intents and purposes, they do not exist to a would-be hacker� You
can turn the firewall function off if needed; however, it is recommended
that you leave the firewall enabled� Disabling the firewall protection will
not leave your network completely vulnerable to hacker attacks, but it is
recommended that you leave the firewall enabled�

USING THE WEB-BASED ADVANCED USER INTERFACE
Configuring Internal Forwarding Settings
The Virtual Servers function will allow you to route external (Internet)
calls for services such as a web server (port 80), FTP server (Port 21), or
other applications through your Router to your internal network� Since
your internal computers are protected by a firewall, computers outside
your network (over the Internet) cannot get to them because they cannot
be “seen”� A list of common applications has been provided in case you
need to configure the Virtual Server function for a specific application�
If your application is not listed, you will need to contact the application
vendor to find out which port settings you need�
Choosing an Application
Select your application from the drop-down list� Click “Add”� The
settings will be transferred to the next available space in the screen�
Click “Apply Changes” to save the setting for that application� To remove
an application, select the number of the row that you want to remove
then click “Clear”�
Manually Entering Settings into the Virtual Server
To manually enter settings, enter the IP address in the space provided
for the internal (server) machine, the port(s) required to pass (use a
comma between multiple ports), select the port type (TCP or UDP),
and click “Apply Changes”� You can only pass one port per internal IP
address� Opening ports in your firewall can pose a security risk� You can
enable and disable settings very quickly� It is recommended that you
disable the settings when you are not using a specific application�
