Configuring Port Trigger Settings

When you run a computer application that accesses the Internet, it typically initiates communications with a computer on the Internet. In some applications, especially games, the computer on the Internet attempts to communicate with your computer. NAT does not normally allow these incoming connections to occur, but you can use port triggering to bypass this. Port triggering is a function that allows incoming communication with specified applications.

The WR850 is already configured with port triggering for some common applications. You can also configure additional port triggers using the Networking – Port Trigger screen.

To access the screen, click Networking > Port Trigger.

To add a Port Trigger entry:

1Enter the name of the application in the Port Trigger Name field. There is a limit of 32 characters for the name.
