Configuring Internal Forwarding settings
The Virtual Servers function lets you 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.
To enter settings into the virtual server:
1 Open the Virtual Servers page, then enter the IP address in the space provided for the
internal (server) machine, and the port(s) required to pass.
2 Select the port type (TCP or UDP), check the Enable box, then click Apply Changes.
Each inbound port entry has two fields with five characters maximum per field that
allows a start and end port range, for example [xxxxx]-[xxxxx]. For each entry, you
can enter a single port value by filling in the two fields with the same value (for
example, [7500]-[7500]) or a wide range of ports (for example [7500]-[9000]). If
you need multiple single port values or a combination of ranges and a single value,
you must use multiple entries up to the maximum of 20 entries (for example,
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 quickly. It is recommended that you disable the settings
when you are not using a specific application.
