Add New Port Forwarding Rule: page 2

Use Port Range: Changes the selection options to allow you to
input a range of ports (if desired).

Internet Port(s): The port number(s) as you want it defined on
the internet. Typically these will be the same as the local port
numbers, but they do not have to be. These numbers will be
mapped to the local port numbers.

Local Computer: Select the IP address of an attached device
from the dropdown menu, or manually input the IP address of a
device.

Local Port(s): The port number(s) that corresponds to the service (Web server, FTP, etc) on a local computer or
device.
For example, you might input
―80‖ in the Local Port(s) field to open a port for a Web server on a computer within
your network. The Internet Port(s) field could then also be 80, or you could choose another port number that will
be used across the internet to access your Web server. If you choose a number other than 80 for the internet Port,
connections to that number will be mapped to 80
—and therefore the Web server—within your network.
