How to block Google DNS on homehub 3000 or 4000

I have a homehub 3000 that I configured to route the internet through opendns to filter all the garbage of this world and protect my young ones ( porn, junk, tiktok ). However my teenage son found way to bypass this by configuring his computer to use Google DNS locally, though bypassing my Router DNS setup ( smart move ), my question is :

How do you block Google DNS on your router, there doesn't seem to be such option in the Homehub 3000, but if someone figured it out please let me know.

If such option is just not possible in the homehub 3000, is it available in the 4000 ? that way I can upgrade.

Thank you

Hi @senuoy ,

I have the HH4K; no specific setting to block a specific dns server IP(s). You can customize the default DNS settings, as you have done on the HH3K. Completely overriding client device-level dns requests may require your own dns server.

You can use the Bell App (Ios or Android), allowing you to block internet access by device for certain times of day. But that may be too heavy-handed.

Cloudflare has a product which may interest you. Cloudflare for Families

I'm clearly no expert, but hopefully this will kick off a discussion and some high-quality information will be posted.

Cheers.

Hi @senuoy,

I've thought more about your situation and looked into it.

The essential problem is that it's just about impossible to defeat client-side dns settings (to force router-only dns settings to be used). There are some complex solutions, but at the end of the day your teenager will simply try any number of dns servers that are freely available if Google dns isn't working.

As recommended by some people, the most effective solution would be to change the admin privileges on his computer.

Two steps:

1. You would need to reset his login credentials to user: he would be locked out of making admin-level changes, like dns settings.

2. Remove the current dns settings and leave them blank. That would force the device to use the router's dns.

He may not be happy about this, but hopefully a conversation beforehand would ease the pain!
