This reminds me of an discussion I had with a user who tried the autorate-ingress feature unsuccessfully, it sems he would have needed an additional toggle to set the lower range for the bandwidth as due to some quirkiness his ingress did not as much get autorated but rather throttled. So @Jonathan and @Toke, is that just an unfortunate sould that can't be helped or does such an additional toggle make some sense (if only as a safety belt and suspenders kind of thing). If yes, I might try to actually test it.

Best Regards
