Host C is download files and Host B is accessing port 2000 for some service. I have no access to the application and servers. Host A is a AS/400.
From the 3-way Handshake, Host B has not yet finish the synchronisation so there is no way Host A knows what kind of files Host B want to download.
You can read RFC 3360 and RFC 793 for more information.
I suspect that the SYN packet source port initiated by Host B is dropped.
That's why whenever Host B receive Host A SYN+ACK packet, it does not know
how to react and reply a RST.
Need to find out the timeout portion.
