(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.

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).

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 
can usually determine this information by contacting the publisher of the application or user 
groups or news groups.
