Follow these directions to create a new rule.

1 In the Rule Summary screen, type the index number for where you want to put the 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. 

2 Click Insert to display this screen and refer to the following table for information on the 

labels.

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.

Rule

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.

Active

This field displays whether a firewall is turned on (Y) or not (N). 

Source IP

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.

Destination IP

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.

Service 

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.

Action

This is the specified action for that rule, either Block or Forward. Note that Block

(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. 

Move

Type a rule’s index number and the number for where you want to put that rule. Click
