D6200 WiFi DSL Modem Router
2. In the Port Forwarding/Port Triggering screen, configure the WiFi DSL modem 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 WiFi DSL
modem router to use the name.
For more information, see Dynamic DNS on page 123.
To access your web server from the Internet, a remote user has to 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.
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 WiFi DSL modem router monitors outbound traffic
looking for a specified outbound “trigger” port. When the WiFi DSL modem router detects
outbound traffic on that port, it remembers the IP address of the local computer that sent the
data. The WiFi DSL modem 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). For more information, see Universal
Plug and Play on page 130.
To set up port triggering, you need to know which inbound ports the application needs. Also,
you need to know the number of the outbound port that triggers 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 ADVANCED > Advanced Setup > Port Forwarding/Port Triggering.
