I was unhappy to find that Traffic Shaping is only a feature of Nebula Pro. This is a basic feature, it doesn't require any continual updates from Zyxel and should not be subscription based. This is a big problem for us.
Thanks for your advice, please be aware that traffic shaping can still work on source iP range the only restriction is you cannot specify the destination IP, Ports,Protocol and Priority in free version. Sorry for any confusions.🙂
