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 P-79X applies the rules in the order that you specify.
When a rule matches the current packet, the P-79X takes the corresponding action and the
remaining rules are ignored. To change your P-79X’s address mapping settings, click Network >
NAT > Address Mapping to open the following screen.
