8.4 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-660H-T1v3s applies the rules in
the order that you specify. When a rule matches the current packet, the P-660H-
T1v3s 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.
