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.
