Ok I found the post where Ron_Case from the Peplink team admits that not limiting the WAN download speed (traffic shaping) and just limiting the upload from the wan upload/download limits page is by design. (again not sure why they decided it should only respect one of the values instead of both, but they probably know better than me why)
So any help accomplishing this would be greatly appreciated, I mean I’m only asking to be able to do basic traffic shaping on a WAN, its a basic SD function on nearly all post 2008 routers, not some wild crazy feature haha, there has to be a way to accomplish this through maybe a workaround?, or CLI?, I’ve seen these things do literal magic, not sure why this is so complicated.
