Hi,

 

I have a Telus T3200M modem/router.  I also have a Google Chromecast, which I understand uses Google DNS regardless of what is set in the router.  I'd like to block Google Chromecast's use of Google DNS, so that it falls back to the router's DNS settings.  It seems like this is possible by setting up a static route (see here or here ), but I don't know if that's possible with the T3200M.  Can anyone advise?

 

Thank you!

P.S. My goal is not to try to use US Netflix, unlike in the links I provided.

I think the bigger question is why do you want to block the DNS? Are you having problems connecting using the Chromecast?

No, my goal is to block youtube on the chromecast device. I can do that if I use an alternate dns (like OpenDNS), but I don't think I can do that with Google's DNS.

So you just want to block it on the Chromecast only and not any other device in the house? I'm not sure there's an option on the Actiontec that would do specifically what you're wanting.

I'd be okay with blocking Google DNS globally on the router.  Many devices (unlike the Chromecast) allow you to specify custom DNS setting, which I could use to override the router set DNS for those devices for which I wish to use youtube.

Any idea on how to block Google DNS, even if its is for all clients of the router? Thank you!

The Chromecast device will have a MAC address so I'm pretty sure you can block that MAC address (device) from accessing certain websites.  Look under the Firewall settings or the Parental Control settings (sorry but I don't have access to my 3200 right now).

Yeah, I thought of that as well.  It's a good idea, except the parent controls only blocks http (not https) according to the router's parent control page text and unfortunately almost everything is https these days.
