The Type, Local and Global Start/End IPs are configured in Menu 15.1.1.1 (described

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.
The description of the other fields is as described above. The Type, Local and Global Start/End IPs are
configured in Menu 15.1.1.1 (described later) and the values are displayed here.
