N150 Wireless Router User Manual

1.Assign your Web server either a fixed IP address or a dynamic IP address using DHCP address reservation, as explained in Using Address Reservation on page 50. In this example, your router will always give your Web server an IP address of 192.168.1.33.

2.In the Port Forwarding screen, configure the router to forward the HTTP service to the local address of your Web server at 192.168.1.33.

HTTP (port 80) is the standard protocol for Web servers.

3.(Optional) Register a host name with a Dynamic DNS service, and configure your router to use the name as described in Using a Dynamic DNS Service on page 51.

To access your Web server from the Internet, a remote user must know the IP address that has been assigned by your ISP. However, if you use a Dynamic DNS service, the remote user can reach your server by a user-friendly Internet name, such as mynetgear.dyndns.org.

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. When the router detects outbound traffic on that port, it remembers the IP address of the local computer that sent the data. The router then temporarily opens the specified incoming port or ports, and forwards incoming traffic on the triggered ports to the triggering computer.

While port forwarding creates a static mapping of a port number or range to a single local computer, port triggering can dynamically open ports to any computer that needs them and can close the ports when they are no longer needed.

Note: If you use applications such as multiplayer gaming, peer-to-peer connections, real-time communications such as instant messaging, or remote assistance (a feature in Windows XP), you should also enable Universal Plug and Play (UPnP) according to the instructions

in Using Universal Plug and Play on page 66.

To configure port triggering, you need to know which inbound ports the application needs. Also, you need to know the number of the outbound port that will trigger the opening of the inbound ports. You can usually determine this information by contacting the publisher of the application or user groups or newsgroups.

To set up port triggering:

1.Select Port Forwarding/Port Triggering under Advanced in the main menu. The Forwarding/Port Triggering screen displays (see Figure on page 62).

2.Select the Port Triggering radio button. The port triggering information displays.
