GLOSSARY
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
& Public port(s) required to pass, 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, e-mail 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.
