Configure Applications and Gaming

Overview

Most well-known Internet applications are supported by Application Layer Gateways (ALGs). ALGs automatically adjust the gateway firewall to allow data to pass without making any custom settings. We recommend that you test your application before making changes in this section.

Applications & Gaming > Port Filtering

Use this window to configure transmission control protocol (TCP) and user datagram protocol (UDP) port filters. These filters prevent a range of TCP/UDP ports from accessing the Internet. You can also prevent PCs from sending outgoing TCP/UDP traffic to the WAN on specific IP port numbers. This filter is not IP address- or MAC address- specific. The system blocks the specified port ranges for all PCs.

Select the Port Filtering tab to open the Applications & Gaming Port Filtering page.

Applications and Gaming Port Filtering Page Description

Use the descriptions and instructions in the following table to configure the port filtering for applications and gaming features used on your residential gateway. Click the Enable checkbox to enable port forwarding for the relevant application. After you make your selections, click Save Settings to apply your changes or Cancel Changes to cancel.
