Set Up Port Triggering - NETGEAR R6200 User Manual

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 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
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.
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
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.
