Hello. My friend visits and we cast from their android phone to my tv, either via Nvidia Shield or Amazon Fire TV Cube. Is there a way to restrict that phone's access such that it can only access those devices, OR exclude access to my NAS? Guest network doesn't work because it excludes access to intranet in its entirety. I don't have any add ons on the router or know how to use scripts on it. Thank you.
