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, select the
port type (TCP or UDP), and click “Apply Changes”. Each inbound port
entry has two fields with 5 characters maximum per field that allows a
start and end port range, e.g. [xxxxx]-[xxxxx]. For each entry, you can
enter a single port value by filling in the two fields with the same value
(e.g. [7500]-[7500] or a wide range of ports (e.g. [7500]-[9000]). If you
need multiple single port value or mixture of ranges and a single value,
you must use multiple entries up to the maximum of 20 entries (e.g.
1. [7500]-[7500], 2. [8023]-[8023], 3. [9000]-[9000]). 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.
