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.
