Table 30-3 Fields In Menu 15.1.1 - ZyXEL Communications ZyWALL 5 User Manual

The Type, Local and Global Start/End IPs are configured in
menu 15.1.1.1 (described later) and the values are displayed here.
Ordering Your Rules
Ordering your rules is important because the ZyWALL applies the rules in the order that you specify.
When a rule matches the current packet, the ZyWALL takes the corresponding action and the
remaining rules are ignored. If there are any empty rules before your new configured rule, your
configured rule will be pushed up by that number of empty rules. For example, if you have already
configured rules 1 to 6 in your current set and now you configure rule number 9. In the set summary
screen, the new rule will be rule 7, not 9.
Now if you delete rule 4, rules 5 to 7 will be pushed up by 1 rule, so as old rule 5 becomes rule 4, old
rule 6 becomes rule 5 and old rule 7 becomes rule 6.
FIELD
Set Name Enter a name for this set of rules. This is a required field. If this field is left blank,
the entire set will be deleted.
Action The default is Edit. Edit means you want to edit a selected rule (see following
field). Insert Before means to insert a rule before the rule selected. The rules
after the selected rule will then be moved down by one rule. Delete means to
delete the selected rule and then all the rules after the selected one will be
advanced one rule. None disables the Select Rule item.
Select When you choose Edit, Insert Before or Delete in the previous field the cursor
Rule jumps to this field to allow you to select the rule to apply the action in question.
You must press [ENTER] at the bottom of the screen to save the
whole set. You must do this again if you make any changes to the
set – including deleting a rule. No changes to the set take place
until this action is taken.
Selecting Edit in the Action field and then selecting a rule brings up the following menu, Menu 15.1.1.1 -
Address Mapping Rule in which you can edit an individual rule and configure the Type, Local and Global
Start/End IPs.
An IP End address must be numerically greater than its
corresponding IP Start address.
