Dear all, when FreeBS sends a SYN-ACK, it never sends an MSS larger than the one received in the SYN. This consideration of the peer's MSS is what the patch removes. Personally, I found this neat although not described in an RFC. The reasoning could be that the client uses its MTU to deduce the MSS and you make the assumption that this is symmetric. Best regards Michael
