Consider a situation where a subscriber's packets are subject to two
levels of NAT, with both NATs operating under the control of the ISP.
An example of this would be a NATing Home Gateway forwarding packets
to a Large Scale NAT. This memo proposes that advantage be taken of
the presence of the second NAT, to offload the burden on the Large
Scale NAT by delegation to the Home Gateway. Enhancements to the
Port Control Protocol are specified to achieve this. The proposed
solution applies also for DS-Lite where the AFTR offloads it NAT to
the B4 element.
