Scenario 1a: DNAT—Packets passing through the Vyatta router

In this scenario, packets originate in Network A and pass through the vRouter.

Note that DNAT operates on the packets before the routing decision. This sequence means that routing decisions based on the destination address are made relative to the translated destination address—not the original destination address; refer to the following figure.
