Chapter 30 NAT Setup
P-792H v2 User’s Guide
326
Ordering your rules is important because the P-792H v2 applies the rules in the
order that you specify. When a rule matches the current packet, the P-792H v2
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.
Note: You must press [ENTER] at the bottom of the screen to save the whole set. You
must do this again if you make any changes to the set – including deleting a
rule. No changes to the set take place until this action is taken.
Selecting Edit in the Action field and then selecting a rule brings up the following
menu, Menu 15.1.1.1
- Address Mapping Rule in which you can edit an
individual rule and configure the Type, Local and Global Start/End IPs.
Note: An IP End address must be numerically greater than its corresponding IP Start
address.
