R6300 WiFi Router 802.11ac Dual Band Gigabit 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 Dynamic DNS on page 97. 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. 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 Universal Plug and Play on page 102. To set up 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 can usually get this information by contacting the publisher of the application or user groups or newsgroups. Advanced Settings 95

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.
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
Universal Plug and Play
on page
102.
To set up 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 can
usually get this information by contacting the publisher of the application or user groups or
newsgroups.
