    If my analysis is correct (see the mail I sent to this thread
    previously), then applying 5850 to the oi_151a9 box will cause the issue
    to disappear -- both peers will then ignore the injected window change
    segment because it has no timestamps. Of course, it's possible that the
    middlebox won't like being ignored and might cause other failures (it
    could still inject RSTs, for example, since those are not required to
    have timestamps).
