Use this screen to change your ZyWALL’s address mapping settings. Not all fields are
available on all models.
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 old rules 5, 6 and 7 become new rules 4, 5 and 6.
