traffic by specifying a filter name and at least one condition on this
window. All of the specified conditions in this filter rule must be satisfied
for the rule to take effect. By default, all incoming IP traffic from the
Internet is blocked when the firewall is enabled.
If you are setting up the incoming IP filtering, click the Incoming link, then
click the Add button.
