28.3.1.2 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. You can change the name for the set in the Set Name field.
Figure 149 Menu 15.1.1 First 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.
28.3.1.3 Ordering Your Rules
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.
Global Start IP This is the starting global IP address (IGA). If you have a dynamic IP, enter 0.0.0.0 as
the Global Start IP .
Global End IP This is the ending global IP address (IGA).
Type These are the mapping types. Server allows us to specify multiple servers of
different types behind NAT to this machine. See later for some examples.
When you have completed this menu, press [ENTER] at the prompt “ Press ENTER to Confirm
or ESC to Cancel: ” to save your configuration, or press [ESC] at any time to cancel.
