address-persistent (Security Source NAT)


Hierarchy Level


Enable the device to assign the same, statically chosen, IP address from a source pool to a host for multiple sessions that require the same source IP address for each session. This option is a global configuration and is applied to all source pools. After a session is established from a host and NAT is performed, the subsequent session from the same host will always use the same translated address.
