Translation (NAT) 

Now let’s look at option 1 in menu 15.1. Enter 1 to bring up this menu. We’ll just look at the 
differences from the previous menu. Note the extra Action and Select Rule fields mean you can 
configure rules in this screen. Note also that the “

?

” in the Set Name field means that this is a required 

field and you must enter a name for the set. 

If the Set Name field is left blank, the entire set will be deleted. 

The Type, Local and Global Start/End IPs are configured in menu 15.1.1.1 (described later) and the 
values are displayed here. 

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 as old rule 5 becomes rule 4, old 
rule 6 becomes rule 5 and old rule 7 becomes rule 6.  

Set Name 

Enter a name for this set of rules. This is a required field. If this field 
is left blank, the entire set will be deleted.
