Port Range Forwarding
Port forwarding can be used to set up public services on
your network. When users from the Internet make certain
requests on your network, the Router can forward those
requests to computers equipped to handle the requests.
If, for example, you set the port number 80 (HTTP) to be
forwarded to IP address 192.168.1.2, then all HTTP requests
from outside users will be forwarded to 192.168.1.2.
NOTE:
You must disable the Router’s DHCP
function to use port forwarding.
You may use this function to establish a web server or FTP
server via an IP gateway. Make sure that you enter a valid
IP address. (You may need to establish a static IP address
in order to properly run an Internet server.) For added
security, Internet users will be able to communicate with
the server, but they will not actually be connected. The
packets will simply be forwarded through the Router.

Port Triggering
Port triggering allows the Router to watch outgoing data
for specific port numbers. The IP address of the computer
that sends the matching data is remembered by the
Router, so that when the requested data returns through
the Router, the data is pulled back to the proper computer
by way of IP address and port mapping rules.
Some Internet applications or games use alternate ports
to communicate between the server and LAN host. When
you want to use these applications, enter the triggering
(outgoing) port and alternate incoming port in the
Port Triggering table. Then the Router will forward the
incoming packets to the LAN host.
Application Name
Enter the name of the application.
Trigger Port Range
Enter the starting and ending port
numbers of the trigger port range.
