9.4 The Address Mapping Screen

Note: The Address Mapping screen is available only when you select Full Feature in
the NAT > General screen.
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. 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 ZyXEL Device's address mapping settings, click Network > NAT >
Address Mapping to open the following screen.
