At this point we already have fully configured firewall object that
has two interfaces (eth0 and loopback), ethernet interface eth0 has
supposed to obtain IP address dynamically via DHCP. The object also
comes with basic firewall policy that blocks all access to the machine
except for ssh and permits all kinds of connections initiated from the
machine.
We need to configure a couple of parameters before we
can activate the policy. Click on "Firewall Settings..." button to
open firewall settings dialog.
