Here we go (assuming that your inside network is 10.10.10.0/24):
object network obj-10.10.10.0
subnet 10.10.10.0 255.255.255.0
object network obj-12.1.1.1
host 12.1.1.1
object-network obj-100.1.1.1
host 100.1.1.1
nat (inside,outside) source dynamic obj-10.10.10.0 obj-100.1.1.1 destination static obj-12.1.1.1 obj-12.1.1.1
It's always good to be more specific on the inside subnet, instead of using the keyword "any" as it can cause translation issue for other interfaces.
