Port translation is essentially the same thing as translational mode, except that the
Layer 4 port on the virtual server can be different from the Layer 4 port on the nodes
being load balanced. The switch takes the traffic and changes the IP address and port
address to that of the severs to be balanced. As with any server load balancing
application, the content must be duplicated on all physical servers.
