23.3.1.2 Ordering Your Rules
Ordering your rules is important because the ZyXEL Device applies the rules in the order that
you specify. When a rule matches the current packet, the ZyXEL Device 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.
you specify. When a rule matches the current packet, the ZyXEL Device 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.
4, old rule 6 becomes rule 5 and old rule 7 becomes rule 6.
