in the VPN Router cache. The minimum number of IP addresses held is one
(1), and the maximum is derived from the maximum number of tunnel
sessions that the VPN Router supports.

Immediate Address Release
if there are a limited number of available
IP addresses and you want the VPN Router to release the IP address back to
the DHCP server immediately. IP addresses from disconnected tunnel
sessions remain unavailable for the time you specify (300 to 7200 seconds).
This delay prohibits immediate reuse by another user that can represent a
security risk.

LAN interface, management interface, or address pool.

potential conflicts, you can verify the current state of this option from the
