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.
