Figure 380   Menu 15.1.1: First Set

"

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 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.
