9.1 Port Forward

Port Forwarding is commonly used to run a publicly accessible server on the LAN by specifying
the mapping of TCP/UDP ports to a local PC.
Application Tab / Port Forward
Click on the Application tab then click on the Port Forward settings tab. This page displays Port
Forward information. Here user can display and set Port Forward Table details. (Start Port,
End Port, Type, Service IP, Service IPv6, Enable and Delete)
To specify a mapping, enter the range of port numbers that should be forwarded locally, and the
IP address to which traffic to those ports should be sent. If only a single port specification is
desired, enter the same port number in the start and end locations for that IP address.

9.2 Port Trigger

Port Triggers are similar to Port Forwarding except that they are not static ports held open all the
time. When the Technicolor Wireless Gateway detects outgoing data on a specific IP port
number set in the Trigger Range, the resulting ports set in the Target Range are opened for
incoming (or sometimes referred to as bi-directional ports) data. If no outgoing traffic is detected
on the Trigger Range ports for 10 minutes, the Target Range ports will close.
