Do you have an example of this particular (mis) configuration? The

.. uhm, again, that isn't very clear. "automatic bypass" isn't
explicitly configured anywhere nor do I see anything in the tproxy2
config which mentions bypass with class 90. So I'm very curious what
exactly it is that people are seeing, with what exact
configuration(s).
