– Allow the reuse of an IP address __ minutes after it is released—Delays the reuse of an IP
address after its return to the address pool. Adding a delay helps to prevent problems firewalls
can experience when an IP address is reassigned quickly. By default, this is unchecked, meaning
the ASA does not impose a delay. If you want one, check the box and enter the number of
minutes in the range 1 - 480 to delay IP address reassignment.

Address Pools
The IP Pool area shows each configured address pool by name, and with their IP address range, for
example: 10.10.147.100 to 10.10.147.177. If no pools exist, the area is empty. The ASA uses these pools
in the order listed: if all addresses in the first pool have been assigned, it uses the next pool, and so on.
If you assign addresses from a non-local subnet, we suggest that you add pools that fall on subnet
boundaries to make adding routes for these networks easier.

•Pool Name—Displays the name of each configured address pool.
•Starting Address—Shows first IP address available in each configured pool.
•Ending Address—Shows the last IP address available in each configured pool.
•Subnet Mask—Shows the subnet mask for addresses in each configured pool.
•Add—Click to add a new address pool.
