Virtual servers
This 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, machines from the
Internet cannot get to them because they cannot be “seen”� If you need
to configure the virtual server function for a specific application, you will
need to contact the application vendor to find out which port settings
you need�
To manually enter settings, enter the IP address in the space provided
for the internal machine, the port type (TCP or UDP), and the LAN and
public port(s) required to pass� Then select “Enable” and click “Set”� 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�
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�
URl blocking
To configure the URL-blocking feature, specify the websites (www�
somesite�com) and/or keywords you want to filter on your network� Click
“Apply Changes” to activate the change� To complete this configuration,
you will need to create or modify an access rule in the client IP filters
section� To modify an existing rule, click the “Edit” option next to the
rule you want to modify� To create a new rule, click on the “Add PC”
option� From the “Access Control Add PC” section, check the option for
“WWW with URL Blocking” in the “Client PC Service” table to filter out
the websites and keywords specified�
schedule Rule
To configure the schedule rule, specify the name, comment, start time,
and end time that you want to filter on your network� This page defines
schedule rule names and activates the schedule for use in the “Access
Control” page�
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 on your network to allow network access to
each or copy the MAC address by selecting the name of the computer
from the “DHCP Client List”� To enable this feature, select “Enable”�
Next, click “Apply Changes” to save the settings�
