Because we cant see the translated packet leaving eth0 after the first attempt at 13:42:23, at this point it is considered to have been lost somewhere between cni0 and eth0. Has the cause of a rocket failure ever been mis-identified, such that another launch failed due to the same problem? if the source IP of the packet is in the targeted NAT pool and the tuple is available then return (packet is kept unchanged). At that point it was clear that our problem was on our virtual machines and had probably nothing to do with the rest of the infrastructure.
