Traditionally IPVS-NAT has worked in the form of destination-NAT,
that is modifying the destination IP address to that of the real-server.
This works well for in a wide range of circumstances.

More recently Full NAT support was added. This modifies
source IP address to that of the linux-director as well
as the destination IP address to that of the selected real-server.

An example of where full NAT may be useful is if a real-server wants to
access a virtual service handled by the linux-director of the real-server.
