--- Comment #43 from Alexandre martins <alexandre.martins at stormshield.eu> ---
I tested on Linux. Its TCP stack just continue to reset the connection by
increment its sequence.

-> SYN (seq 1)
<- SYN/ACK (seq 80 ACK 1)
-> ACK (seq 1 ACK 81)

-> [DATA] (seq 1 ACK 81)
<- [DATA 100] (seq 81)
<- FIN (delayed/lost/ignored/...)
-> [DATA]
<- RST (seq 181)
-> [DATA]
<- RST (seq 182)
-> [DATA]
<- RST (seq 183)
-> [DATA]
<- RST (seq 184)
-> [DATA]
