11.6 Address Mapping

Address mapping can map local IP Addresses to global IP addresses. 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.
