Port forwarding configures a device (modem, router, or gateway) to allow a computer, application, or a service on the Internet to communicate with a specific computer on a private local area network (LAN).
Port forwarding sorts the data from the Internet source to the correct port on your network. Port forwarding is commonly used for online gaming, VPN setup, FTP setup, remote computer software, and Web server hosting.
Before you begin: Make sure you have the port information from the manufacturer or service that requires port forwarding. This normally includes the protocol, port start, port end, and port map.
Note: The Actiontec GT784WNV security screens and prompts may vary slightly from these directions depending on when you purchased your gateway and the firmware loaded on it.
To set up port-forwarding for the Actiontec GT784WNV:
Open a Web browser like Internet Explorer.
Enter http://192.168.1.1 in the Address field of the browser.
Enter your current user name and password and click OK. If you didn't change the user name and password during installation, enter admin in the User Name field and password in the Password field. Note: If you can't remember your user name or password, you will need to reset your Actiontec GT784WNV to the default settings and reconfigure your home network.
Select Advanced Setup from the top navigation.
From the left navigation, select Port Forwarding.
Under 1. Set the LAN port and IP Information:
Enter the starting port for the local computer

Enter the IP address of the local computer
Under 2. Set the remote port and IP information (optional):
Enter the starting port coming from the web
Enter the ending port coming from the web
If you want all access from the web to route to this port enter 0.0.0.0 in the Remote IP Address field
Click Apply to save the new settings. A confirmation page displays your new port-forwarding rule.
