Restrict access to specific device on LAN

[markc6123]

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.

If may be possible using custom IP Tables scripting to allow certain WiFi clients or Guest Network clients to have access to certain or a single main LAN client. Or one can use YazFi and it's custom scripting to accomplish letting Guest Network client(s) access to a main LAN client. Use the search feature to find many past discussions on using custom scripting to manage IP Tables. Or see the following links for YazFi. Note that YazFi does not work with AiMesh nodes.
