Now let’s look at option 1 in menu 15.1. Enter 1 to bring up this menu. We’ll just look at the differences
from the previous menu. Note the extra
Action
and
Select Rule
fields mean you can configure rules in this
screen. Note also that the [?] in the
Set Name
field means that this is a required field and you must enter a
name for the set. If the
Set Name
field is left blank, the entire set will be deleted.

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 Prestige applies the rules in the order that you specify. When a
rule matches the current packet, the Prestige 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.
