address-pooling (Security Source NAT)


Hierarchy Level


The address-pooling paired and address-pooling no-paired options in a source NAT pool enable you to override the global address-persistent configuration and to control the IP addressing in the pool. When either address pooling-paired or address-pooling no-paired is configured in a NAT source pool, the address-persistent configuration is disabled for that pool.

Use the address-pooling paired option in source NAT pools with port translation for applications that require all sessions associated with one internal IP address to be translated to the same external IP address for multiple sessions. (The default behavior for a source NAT pool with port translation pools is address-pooling no-paired.)

Use the address-pooling no-paired option in source NAT pools without port translation for assigning IP addresses using a round-robin fashion. (The default behavior for a source NAT pool without port translation is address-pooling paired.)
