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." You will need to contact the application vendor to find out
which port settings you need.
Entering Settings into the Virtual Server
To enter settings, enter the IP address in the space provided for the
internal (server) machine, and the port(s) required to pass. Then select
the port type (TCP or UDP), check the "Enable" box, and click "Apply
Changes". Each inbound port entry has two fields with five 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 values or a
combination 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.
