In this document is described how the NAT function at the Palo Alto.
Has anything changed in the 5, in contrast to 4.1er?
So far, the destination NAT zone was generally on the incoming interface as the source and destination zone.
In the document is on page 20 (case3) and page 28 (Destination NAT) is the NAT-destination once (untrust / trust) and once untrust/ untrust with a service port.
Which act as is now correct?

The general concept of D-NAT for any traffic is to verify source/destination zone ( forward lookup) and then firewall will evaluate the NAT policy. As a result the policy applied from Untrust-L3 to Untrust-L3. But page no-28 explained the NAT in VW mode. In VW mode IP address configured into Route-1 & router-2. The PA firewall is acting as a transparent device for R-1 and R-2. so, that is the reason D-NAT policy is applied from VW-Untrust to VW-trust here here.
