• 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 does not need to 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.

Configure 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 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 will provide the service. The server
computer has to always have the same IP address.
Tip: To ensure that your server computer always has the same IP address,
use the reserved IP address feature of your product.
