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.
