--- Comment #12 from Andreas Pflug <pgadmin at pse-consulting.de> ---
Well applying routing to a non-routable protocol (in the sense of normal IP
routing) seems not too sensible in any case. Maybe omitting 224.0.0.0/4 from
routing unless it's specified explicitely might be a solution. Should be
probably discussed elsewhere.


In my very first post, I mentioned an early pass out quick wouldn't help
either: I tested again, and now it works, maybe not flushing the rules was the
problem back then.


  pass out quick carp from {(self)} to 224.0.0.18

is the fix for misformed CARP packets.
