Dear Simon,
Thank you for your message.
You are right, I misread the statement, and the exam correction is correct.
N2 operates as a NAT for IPv4 (with internal ports towards observation point O1), so as you said H6 is reachable.

For the packet from H1 to H6, the correct destination IP adress for nodes O7, O8, O1, and O11 is z6 = 8.2.7.11
For the packet from H5 to H6, the correct destination IP adress for nodes O12, O9, O1, and O11 is z6 = 8.2.7.11

Sorry for the inconvenience and thank you for your remark.
