I have a Hisense TV. I was wondering if there’s an easy way to firewall their TV so that it only has access to Google Store and Netflix? Make it so the TV can’t reach anything else?
I don’t currently have any firewall. I have ddwrt as my main router. I can whip up a pihole if needed.
I did some work on locking down an Android tablet, found it quite hard to do. With CDNs etc in play, the IP ranges that need to be opened are quite vast and generic (i.e. lots of cloud providers that host half the Internet).
I used Squid HTTP proxy for URL inspection, but still, many generic domains being connected to. And I found whether an app, including some Google system ones didn’t always respect the device’s proxy settings and would simply fail.
For TVs, I’ve kinda gone meh, and isolated them from other devices, but given them Internet access.
ok, thanks for sharing your experience. Super useful to have someone go down a route before me.
