Whether the reaction from the FreeBSD side is= OK not not depends on SEG.SEQ of the received ACK segments. Unfortunately, tcp= dump doesn't how SEG.SEQ for the ACK segments. Please note that https://tools.ietf.org/html/rfc793#section-3.9, page 69, specifies the conditions under which a received TCP segment is acceptable. = If the received ACK is not acceptable (this depends on SEG.SEQ), an ACK as the= one being sent has to be sent. So seeing the SEG.SEQ of the ACK segments is crucial here. --=20 You are receiving this mail because: You are the assignee for the bug.=
