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 N1 Vision 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 .
Enter an IP address of the computer on which the application will be
running . 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 (for
multiple ports, each single port or port range may need to be on
separate rows), select the port type (TCP, UDP, or BOTH), 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 .
