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
