my ASA configuration as below:
object network test_internal
range 10.1.1.200 10.1.1.254
object network test_external
range 188.8.131.52 184.108.40.206
object network test_pat
range 220.127.116.11 18.104.22.168
nat (inside,outside) source dynamic test_internal test_external
nat (inside,outside) source dynamic test_internal pat-pool test_pat
while one host of 10.1.1.x access to internet it will mapped to one of 203.94.35.x, absolutely real IP is less than mapped IP pools.
my question is: does it possible configure some parameter on the ASA, the mapped IP address could being changed frequently while hosts access to internet?
