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.
