Chapter 8 Network Address Translation (NAT)

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.

 for port numbers commonly used for particular services.

Note: If you do not assign a Default Server IP Address, the Prestige discards all 

packets received for ports that are not specified in this screen or remote 
management.

To change your Prestige’s port forwarding settings, click the NAT link under Network and 
the Port Forwarding tab. The screen appears as shown.
