I know that ack packets are one part of the two-way TCP/IP communication. However sending ack packets with an originating IP of 127.0.0.1 to any non local (! 127.0.0.0/8) IP shouldn't happen, as they will never get back to (or at least be accepted by) the sender. So in my mind it is not normal behaviour or it is some kind of bug.
