NAT is used for one-to-one mapping of addresses.

There are four private IP addresses configured on the Ethernet side of the
DSL router with NAT static mappings to four public IP addresses.

The Ethernet (e0) interface is in the private address space and the DSL
interface is in public address space.

The next hop router for the clients is the Ethernet IP address of the DSL
router.
