@RN222 Okay, I know the SANS guide says to make these rules "quick" but as far as I know, they actually do not work when they're quick. I'm not sure if that was considered a bug, and/or if it still applies, but it was definitely true at one point. And My floating rules that assign traffic to limiter queues are just normal floating rules (i.e. not quick). Mine are also match rules, not pass, which I also believed was necessary at least at one point.
So I would advise that you first make all four of these rules "normal" (i.e. non-quick) floating rules. And if that still does not work, try making them all match rules as well.
