**NAT target** - This defines the way NAT is implemented for use during loopback. Masquerade is the default, but involves an additional lookup. ad the mapping of done towards an interface. SNAT is minutely faster, as the NAT mapping points directly to the destination IP and so it bypasses the lookup stage. However, SNAT is less reliable than Masquerade. | **NAT target** - This defines the way NAT is implemented for use during loopback.
