 I should have written that the connection is closed nicely, with a FIN
 packet (I just re-checked). Please note that the conntrack keeps closed
 connection for a while exactly like a normal connection, and with the
 [ASSURED] flag but it adds a TIME_WAIT flag to closed connections.

 Yes, it could have been a good explanation.
