I am new with HAProxy and I am running an experiment where I want HAProxy to send SYN to the backend as soon as Client sends SYN. Currently, I see that HAProxy completes 3-way Handshake with Client first and then starts 3-way with backend. My aim is to parallelize these 2 handshakes.
I believe this is because of native DDOS prevention against SYN flood from HAProxy. Is there a way to solve this?
