McAfee INTERNET SECURITY SUITE 2008 User Manual page 103

Banning computer connections
You can add, edit, and remove banned IP addresses in the
Trusted and Banned IPs pane, under
Computers that are associated with unknown, suspicious, or
distrusted IP addresses can be banned 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 certain an Internet connection poses a specific
threat. Ensure that you do not block important IP addresses, such
as your DNS or DHCP server, or other ISP-related servers.
Depending on your security settings, Firewall can alert you when
it detects an event from a banned computer.
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.
