Firewall

A firewall protects your connected devices against malicious
incoming traffic from the Internet. The firewall cannot be disabled,
but the following settings are available.
Firewall - MAC/IP/Port Filtering
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 by
default by selecting the appropriate option from the Default Policy
dropdown.
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 the "Add Custom Application" button,
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.
Applications: Use these check boxes to deny or allow access to
the Internet for each application, as an exception to the selected
Default Policy of accepting or dropping Internet traffic.
