I want to stop sites that provides audio and video content that provides foreign languages

[kumarr98]

I dont see a way to customize firewall. 

I would like to validate the content coming in to see if its content from Russia / China /Japan and block / allow the sites accordingly? How would I do this today on my Google WiFi Router? There are many devices. While I can do it on browsers, I want to see how I can control this firewall at WiFi level. Please, advise.

Thanks,

Rajan

Hello @kumarr98 

This is not possible using the existing Google WiFi system alone. You might be able to achieve some degree of success by implementing a custom DNS server inside your network and having it filter responses accordingly. Something like a PiHole, for example (which is designed to filter requests to ad-serving networks). But, as browsers are now starting to do much of their own DNS resolution directly, using DNS-over-HTTPS, even this may not be as effective as you are asking for.

Hi, everyone.
As we haven't had any activity here recently I'm going to go ahead and close the thread. If you have more to add, feel free to start a new discussion.
