User-Defined Address Mapping Sets

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.

Ordering Your Rules

Ordering your rules is important because the HomeSafe applies the rules in the order that you specify. When a rule matches the current packet, the HomeSafe 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.
