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.
Modes
The following table shows the modes in which this feature is available:
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.
Fields
• 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.
• Edit/Delete—Click to edit or delete an already configured address pool.
Modes
The following table shows the modes in which this feature is available:
