Chapter 13 Firewall Configuration
DESCRIPTION
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 above.
This is your firewall rule number. The ordering of your rules is important as rules are
applied in turn.
Click a rule's number to go to the Firewall Edit Rule screen to configure or edit a
firewall rule.
This field displays whether a firewall is turned on (Y) or not (N).
This drop-down list box displays the source addresses or ranges of addresses to
which this firewall rule applies. Please note that a blank source or destination
address is equivalent to Any.
This drop-down list box displays the destination addresses or ranges of addresses
to which this firewall rule applies. Please note that a blank source or destination
address is equivalent to Any.
This drop-down list box displays the services to which this firewall rule applies.
Please note that a blank service type is equivalent to Any. See for more
information.
This is the specified action for that rule, either Block or Forward. Note that Block
means the firewall silently discards the packet.
This field tells you whether a schedule is specified (Yes) or not (No).
This field shows you whether a log is created when packets match this rule
(Enabled) or not (Disable).
This field tells you whether this rule generates an alert (Yes) or not (No) when the
rule is matched.
Type the index number for where you want to put a rule. For example, if you type "6",
your new rule becomes number 6 and the previous rule 6 (if there is one) becomes
rule 7.
Click Insert to add a new firewall rule before the specified index number.
Click Append to add a new firewall rule after the specified index number.
Type a rule's index number and the number for where you want to put that rule. Click
Move to move the rule to the number that you typed. The ordering of your rules is
important as they are applied in order of their numbering.
