How Port Forwarding Differs from Port Triggering

The following points summarize the differences between port forwarding and port triggering:
• Port triggering can be used by any computer on your network, although only one
computer can use it at a time.
• Port forwarding is configured for a single computer on your network.
• Port triggering requires 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 triggering requires specific outbound traffic to open the inbound ports, and the
triggered ports are closed after a period of no activity.
• Port forwarding 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/Port Triggering screen to configure the wireless modem router 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 provide, 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: To ensure that your server computer always has the same IP address,
use the reserved IP address feature of your N750 Modem Router.
