In a 3 NIC configuration, you can often set up NAT on the DMZ port, but normally, the DMZ is used for public servers - thus they need public IP addresses anyway - so why use NAT there. You do get to specify rules which allow traffic to/from the DMZ port just like you would for the internal/trusted port and you can allow traffic from the DMZ port to the trusted port or just use specific IP addrs which would be for severs on either internal or DMZ ports.

Many of the firewall appliances have 3 ethernet ports, plus many of the software only implementations allow 3 NICs to be used.
