I am trying to configure my RAX50 Wifi Router to block certain websites but even after following the documentation, I am still able to access the sites. Is the router shite or am I missing something?

Scroll to Page 49

Side note: trying to block Instagram, Snapchat and other social media sites

Note: Keyword blocking only works for website URLs that begin with http.:// only. It
does not work for URLs that begin with https://

Almost every site will use https.

Get a free OpenDNS account and then set up your router to use the OpenDNS servers. As a bonus your internet might feel snappier.

Edit: L-O-L, https is so ubiquitous now that TD won't allow me to write "http" with a : after it. It automatically replaces it with https

Awesome advice, set up my free account and now the websites are being blocked!

Just keep in mind it's incredibly easy to bypass OpenDNS blocking.

How do you bypass it?

Great! Be sure to use their dynamic IP updater program.

You can set whatever device you are using to use a different DNS server, bypassing OpenDNS altogether.

What you have done is tell your router to hand out the OpenDNS server address to devices that connect to it, if they are configured to accept the settings. All it does is whenever a device asks for instagram.com, it uses opendns to translate that to an IP address and then loads the site. You have opendns denying those requests, but the device can just as easily ignore the router-provided DNS server and use a different one to get to instagram. A device can still visit any random IP address it wants.

For more strict blocking you will need something more active and I'm not sure your router will do it. You'd need parental controls or other content filtering.

I don't think they're going to know how to configure their own DNS settings, so I should be good for a while.

I would even argue that were they to figure it out, then they have learned a valuable life skill while circumnavigating your parental restriction.

Life achievement that comes with an unlock. *you now have access to social media*

Good call. I had to learn a little electrical and basics of alarm systems so I could sneak out when I was a teenager. I earned that...right up until the cops caught me one night.

You have about (20 - age) days until they figure how to change their DNS settings

They won't really have to if they (for example) use a free VPN program which will use its own DNS. These are getting to be pretty common now. It all depends on your kids I suppose, if you're just trying to prevent little kids from accidentally straying into social media and seeing something they shouldn't then it'll probably be fine, but if you're dealing with someone (at any age) who is intentionally trying to bypass it, it will be pretty trivial for someone with no skills and a moment of research.

When they figure out how to do that, then it's time for a REAL firewall. Rewrite rule; any tcp/udp 53 -> where I damn well say it goes.

If they're using cell phones, don't waste your time. They'll figure out how to turn off wifi when they're at home before dinner. Then they'll be using DNS from AT&T, etc.

It was literally under 2 hours and they had downloaded a VPN

You should have added all sites that provide VPN clients to your block list.

Wish that was a category within OpenDNS.

I recently setup a docker environment in the cloud with DigitalOcean for this exact purpose. I pay $6/month and run 3 containers.

1. Wireguard VPN server
2. Wireguard GUI
3. AdGuard home

Adguard acts as a DNS server and blocks access to social media services and malicious sites. On its backend I use 1.1.1.3 and 1.0.0.3 for DNS. These filter out adult sites and Malware.

The VPN clients (kids’ cellphones) are configured to use the AdGuard server for DNS. The VPN is configured on their phone to be on automatically and they are restricted from using the app/configuring the connection settings via screen time.

So far this setup has worked really well for us. I wish it were easier to protect our kids online but it is what it is…
