RST packet is sent from probe of load balancer.
The probe use RST to disconnect a TCP connection that established 3 way handshake. If I use an software to monitor some paket, the software will detect some errors by RST paket. I hope we can use FIN sequence to close the TCP connection.
Thank you for the feedback. Can you clarify please if you are asking for the health probe to close the connection
a) WITH a 4 way close or
b) WITHOUT a 4 way close and send RST instead?
My answer is a.
Some applications monitor a packet whether there is RSTpacket. If the probe send RST, that monitor will be fail.
@hisashima load balancer uses (a) today. why do you need the behavior described in (b). can you elaborate on the scenario and impact please?
Answer is b. The probe without a 4way close and send only RST packet.
