Application Example: Make 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.  To make a local web server public: 1. Assign your web server either a fixed IP address or a dynamic IP address using DHCP address reservation. In this example, your router always gives your web server an IP address of 192.168.1.33. 2. In the Port Forwarding/Port Triggering 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. To access your web server from the Internet, a remote user has to know the IP address that your ISP assigned. 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. Set Up 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. 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. 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). See Universal Plug and Play on page 104. To configure port triggering, you need to know which inbound ports the application needs, and the number of the outbound port that will trigger the opening of the inbound ports. You Security 75

Application Example: Make 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.
To make a local web server public:
1.
Assign your web server either a fixed IP address or a dynamic IP address using DHCP
address reservation.
In this example, your router always gives your web server an IP address of 192.168.1.33.
2.
In the Port Forwarding/Port Triggering 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.
To access your web server from the Internet, a remote user has to know the IP address
that your ISP assigned. 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.
Set Up 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.
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.
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). See
Universal Plug and Play
on page
104.
To configure port triggering, you need to know which inbound ports the application needs,
and the number of the outbound port that will trigger the opening of the inbound ports. You
