The firewall lets you set your protection level through IPv4 Firewall Protection, for
example. By default, with the Low setting, all services are allowed. If you select
Medium or High protection, the firewall will block all services except those listed in
the List of Allowed Services at the bottom of the page. Select the desired
protection level, and click Save.
The higher protection levels will make it harder for attackers to penetrate your
network. You may find that if you select one of these levels, that some Internet
activities may fail. If that is the case, you may need to use a lower level of
protection during those activities.
Note that in order to play some games, you may need to turn protection off.
When enabled, Port Scan Detection and IP Flood Detection will generate reports
in the Firewall Log if they detect their respective attacks.
