3. Your web server at 192.168.1.123 receives the request and composes a return message
with the requested web page data. Your web server then sends this reply message to your
router.
4. Y
our router performs Network Address Translation (NAT) on the source IP address, and
sends this request message through the Internet to the remote computer, which displays the
web page from www.example.com.
To configure port forwarding, you need to know which inbou
nd ports the application needs.
You can determine this information by contacting the publisher of the application or the
relevant user groups and newsgroups.
How Port Forwarding Differs from Port Triggering
The following points summarize the differences between port forwarding and port triggering:
Port triggerin
g can be used by any computer on your network, although only one
computer can use it at a time.
Port forward
ing is configured for a single computer on your network.
Port triggering do
es not require that you know the computer’s IP address in advance. The
IP address is captured automatically.
Port forwarding requires that
you specify the computer’s IP address during configuration,
and the IP address can never change.
Port triggerin
g requires specific outbound traffic to open the inbound ports, and the
triggered ports are closed after a period of no activity.
Port forward
ing is always active and does not need to be triggered.
Set Up Port Forwarding to Local Servers
Using the port forwarding feature, you can allow certain types of incoming traffic to reach
servers on your local network. For example, you might want to make a local web server, FTP
server, or game server visible and available to the Internet.
Use the Port Forwarding screen to configure the route
r to forward specific incoming protocols
to computers on your local network. In addition to servers for specific applications, you can
also specify a default DMZ server to which all other incoming protocols are forwarded.
Before starting, you need to determine which type of service, application, or game you want
to pro
vide, and the local IP address of the computer that provides the service. The server
computer has to always have the same IP address.
To set up port forwarding:
Tip: T
o ensure that your server computer always has the same IP address,
use the reserved IP address feature of your router.
