Now look at option 1 in menu 15.1. Enter 1 to bring up this menu. 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.
Note: The entire set will be deleted if you leave the Set Name field blank and press
[ENTER] at the bottom of the screen.

Note: The Type, Local and Global Start/End IPs are configured in menu 15.1.1.1
(described later) and the values are displayed here.
Local End IP Local End IP is the ending local IP address (ILA). If the rule is for all local IPs, then the
start IP is 0.0.0.0 and the end IP is 255.255.255.255.
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 discussed above. Server allows us to specify multiple
servers of different types behind NAT to this machine. See later for some examples.
Once you have finished configuring a rule in this menu, press [ENTER] at the message “Press ENTER
to Confirm…” to save your configuration, or press [ESC] to cancel.
