Configuring Address Mapping

Ordering your rules is important because the Business Secure Router applies the
rules in the order that you specify. When a rule matches the current packet, the
Business Secure Router takes the corresponding action and the remaining rules
are ignored. If there are any empty rules before your new configured rule, your
configured rule is pushed up by that number of empty rules. For example, if you
have already configured rules 1 to 6 in your current set and you configure rule
number 9. In the set summary screen, the new rule becomes rule 7, not 9. If you
delete rule 4, rules 5 to 7 are pushed up by 1 rule, so old rules 5, 6, and 7 become
new rules 4, 5, and 6.
To change the NAT address mapping settings, click SUA/NAT, then the Address
Mapping tab. The screen appears as shown in
