Banning computer connections
You can add, edit, and remove banned IP addresses in the
Banned IPs pane.
You can ban computers that are associated with unknown,
suspicious, or distrusted IP addresses from connecting to your
computer.
Since Firewall blocks all unwanted traffic, it is normally not
necessary to ban an IP address. You should ban an IP address
only when you are sure that an Internet connection is a threat.
Make sure that you do not block important IP addresses, such as
your DNS or DHCP server, or other ISP-related servers.
Add a banned computer connection
You can add a banned computer connection and its associated IP
address.
Note: Ensure that you do not block important IP addresses, such
as your DNS or DHCP server, or other ISP-related servers.
