Netgear N300 사용자 설명서

Your 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 inbound ports the application needs. 
You usually can determine this information by contacting the publisher of the application or 
the relevant user groups or news groups.

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.

With port triggering, the router 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.

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 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.

To ensure that your server computer always has the same IP address, 

use the reserved IP address feature of your product.
