Chapter 1 Configuring IP Addresses for VPNs
Configuring an IP Address Assignment Policy
– Allow the reuse of an IP address so many 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 the ASA does not impose
a delay. This configurable element is available for IPv4 assignment policies.
Use one of these methods to specify a way to assign IP addresses to remote access clients.
• Configuring IPv4 Address Assignments at the Command Line
• Configuring IPv6 Address Assignments at the Command Line

vpn-addr-assign {aaa | dhcp | local [reuse-delay
minutes]}

hostname(config)# vpn-addr-assign aaa
Example:
hostname(config)# vpn-addr-assign local reuse-delay 180
Example:
hostname(config)# no vpn-addr-assign dhcp
Enables an address assignment method for the ASA to use
when assigning IPv4 address to VPN connections. The
available methods to obtain an IP address are from a AAA
server, DHCP server, or a local address pool. All of these
methods are enabled by default.
For local IP address pools, you can configure the reuse of
an IP address for between 0 and 480 minutes after the IP
address has been released.
Use the no form of the command to disable an address
assignment method.
Command Purpose
ipv6-vpn-addr-assign {aaa | local}
Example:
hostname(config)# ipv6-vpn-addr-assign aaa
Example:
hostname(config)# no ipv6-vpn-addr-assign local
Enables an address assignment method for the ASA to use
when assigning IPv6 address to VPN connections. The
available methods to obtain an IP address are from a AAA
server or a local address pool. Both of these methods are
enabled by default.
Use the no form of the command to disable an address
assignment method.
