10.5 Configuring Address Mapping

Ordering your rules is important because the Prestige applies the rules in the order that you specify. When a
rule matches the current packet, the Prestige 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 Prestige’s Address Mapping settings, click SUA/NAT, then the Address Mapping tab. The
screen appears as shown.
