IP Permit List Default Configuration

You can specify the same IP address in more than one entry in the permit list if the masks are different.
The mask is applied to the address before it is stored in NVRAM, so that entries that have the same effect
(but different addresses) are not stored. When you add such an address to the IP permit list, the system
displays the address after the mask is applied.
