You can Enable or Disable the Mac/IP/Port Filtering feature as
needed to block certain Internet traffic. If this setting is enabled,
you can then choose whether traffic is Accepted or Dropped

Policy drop-down box.

Click Firewall > MAC/IP/Port Filtering tab.
Select Enable.
Select the Default Policy:
• Accepted — Internet traffic is allowed by default. Only
traffic from the selected applications will be blocked
from accessing the Internet. Traffic is identified by port
numbers. Some applications are pre-defined. You can
define additional applications by clicking Add Custom
Application, but you need to know details of the traffic
used and generated by the applications you wish to define.
In particular, you need to know the port numbers and the
protocol (TCP, UDP) used by outgoing traffic.
• Dropped — Internet traffic is blocked by default. Only traffic
from the selected pre-defined or custom applications are
allowed to access the Internet.
Click Apply.
