15.5 Configuring Address Mapping

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.
To change your ZyWALL's Address Mapping settings, click SUA/NAT, then the Address Mapping
tab. The screen appears as shown.
