the Start IP is 0.0.0.0 and the End IP is

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 that, this screen is not read only, so we have extra Action and Select Rule
fields. 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.
If the Set Name field is left blank, the entire set will be deleted.
