extract the internal IP from the incoming packet header

The internal IP is not sent in the header, only the external IP of the NAT box is. Only the NAT box knows the internal IP. The NAT box knows which internal client to direct any given packets to becuse it remembers the PORT (not IP) that it negotiated for that client transaction.
