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.
