Port forwarding. You can use this feature to allow certain types of incoming traffic to 

reach servers on your local network. For example, you might make a local Web server, 
FTP server, or game server visible and available to the Internet.

Port triggering. Port triggering is a dynamic extension of port forwarding that is useful in 

these cases:

More than one local computer needs port forwarding for the same application (but not 
simultaneously).

An application needs to open incoming ports that are different from the outgoing port.

Port forwarding and port triggering are described in the following sections.

Port Forwarding to a Local Server

Using the port forwarding feature, you can allow certain types of incoming traffic to reach 
servers on your local network. For example, you might 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. The 
DMZ server is configured in the WAN Setup screen, as discussed in 

Before starting, you need to determine which type of service, application, or game you will 
provide, and the local IP address of the computer that will provide the service. Be sure the 
computer’s IP address never changes.

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

use the reserved IP address feature of your JWNR2000v2 router. See 

71 for instructions on how to use 

reserved IP addresses.
