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.

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
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.
