I have OpenWRT 22.03 installed and am soon upgrading my TV. Its a new LG and I want to block the surveillance on a network level. What is they 'right' way to do this? At the moment the OpenWRT router is vanilla and does the DNS and DHCP, I have a redirect for all port 53 traffic to the router to stop other DNS being used. I'd prefer not to install adblock or pihole.
@darksky, if I understand correctly, VLAN will allow the device to access the internet, but not to "see" the rest of the network (which was one of my question in my post here: Wireless bridge with ASUS RT-10 B1). Does VLAN reduce the performances of the connection?
Would it be equivalent to some VPN services that offer some DNS filtering?
I should keep that in my when I update my material then (besides being old and slow, my ASUS RT seems not compatible with VLAN, according to the page here: Wireless bridge with ASUS RT-10 B1) . I will try to learn more about VLANs, but it seems that some interesting things can be managed (separation between different wifi clients; work and home PCs... Apologies if I am just discovering this, routing is a new world to me)
Communication with third parties is mentioned in the optional agreements you can chose to accept when you initialise/set your TV up. If you change your mind, and wish to revoke those agreements, you should be able to "remove" your agreement from the configuration screens, but this will likely disable some features.
my skills (your thread seems way above my current level of knowledge)
Although I have really appreciated you reply, since it helps me along the path of starting to understand what I regarded as "black boxes", I need much more work before being ready for such a configuration. Let's hope in the future ...
Not what you asked for, but I operate my nominally smart tv as simple hdmi monitor... in my case that just moves the problem around a bit, but apple was spying on me anyways (I use 'itunes', erm apple movies as it seems to be called currently).
