Firewall Rules
Storage
Space in Use This read-only bar shows how much of the IAD's memory for recording
firewall rules it is currently using. When you are using 80% or less of the
storage space, the bar is green. When the amount of space used is over
80%, the bar is red.
Packet
Direction Use the drop-down list box to select a direction of travel of packets for
which you want to configure firewall rules.
Create a new
rule after rule
number Select an index number and click Add to add a new firewall rule after the
selected index number. For example, if you select “6”, your new rule
becomes number 7 and the previous rule 7 (if there is one) becomes rule
8.
The following read-only fields summarize the rules you have created that
apply to traffic traveling in the selected packet direction. The firewall rules
that you configure (summarized below) take priority over the general
firewall action settings in the General screen.
# This is your firewall rule number. The ordering of your rules is important
as rules are applied in turn.

box to enable the rule. Clear the check box to disable the rule.
