However, you might need to allow a client computer on the Internet to initiate a connection to a server computer on your network. Normally, your router ignores any inbound traffic that is not a response to your own outbound traffic.
NETGEAR Wireless-N 300 Router JWNR2000 User Manual 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 does not need to know the computer’s IP address in advance. The IP address is captured automatically.
NETGEAR Wireless-N 300 Router JWNR2000 User Manual To configure port forwarding to a local server: 1. Select Port Forwarding/Port Triggering under Advanced in the main menu. The Port Forwarding/Port Triggering screen displays. Figure 5-1 2. From the Service Name list, select the service or game that you will host on your network. If the service does not appear in the list, see the following section, “Adding a Custom Service.” 3.

Application Example: Making a Local Web Server Public If you host a Web server on your local network, you can use port forwarding to allow Web requests from anyone on the Internet to reach your Web server.
NETGEAR Wireless-N 300 Router JWNR2000 User Manual Configuring 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. When port triggering is enabled, the router monitors outbound traffic looking for a specified outbound “trigger” port.
NETGEAR Wireless-N 300 Router JWNR2000 User Manual 2. Select the Port Triggering radio button. The port triggering information displays. Figure 5-4 3. Clear the Disable Port Triggering check box.
