From Study Guide:
TCP state -> Value
NONE -> 0
ESTABLISHED -> 1
SYN_SENT -> 2
SYN -> & -> SYN/ACK -> 3
FIN_WAIT -> 4
TIME_WAIT -> 5
CLOSE -> 6
CLOSE_WAIT -> 7
LAST_ACK -> 8
LISTEN -> 9

When a session is closed by both the sender and receiver, FortiGate keeps that session in the session table for a few seconds, to allow for any out-of-order packets that might arrive after the FIN/ACK packet. This is the state value 5.
