I'm not using a browser. I'm using a native android app.
that app on my Android phone and my iphone 8 has the ads blocked.
But on my other android phone (realme 6) the apps go through.
What I'm trying to understand is why Pihole doesn't block the ads to the Realme 6 phone.
Still, activate Wireguard on that Realm phone.
In that situation it doesn't route the normal way but from your phone through the wireguard VPN tunnel to PiHole.
Installed PiVPN and Wireguard.
Added the client and activate it on the android phone.
No ads are blocked.
This is very strange.
Any help on this matter is much appreciated!
Try entering an unused IP from your LAN range in DNS 2 on the phone.
Ok. I will try that tomorrow.
What's the purpose behind this?
To fill up that spot and prevent the device from using Google as a second DNS. It's not clear that Google does this, but filling the spot is a step to try.
Take your time, switch back to zero, uninstall PiHole and PiVPN
pivpn -u and pihole uninstall
Reboot your raspberry
Read this page GitHub - pi-hole/pi-hole: A black hole for Internet advertisements
install pihole
point your routers DNS tothe ip address of your raspberry
do a pivpn -a -p to get rid of the admin dasboard password
See if it works. Watch ip.of.your.raspberrypi/admin
Then install pivpn with standard options
Do the portforwarding on your router or it won't work
When pivpn doesn't act as expected read this page FAQ · pivpn/pivpn Wiki · GitHub
PS
When something does not work as expected I always step back and reset, read information and restart.
In most cases everything works perfect in a second attempt.
Maybe because I have overseen something or whatever.
Searching what causes trouble in software setup takes mostly more time then restart from the beginning.
I agree. I will try this.
I'm just surprised that pihole works for all my other devices, except this one. Seems that there's something else going on.
I think if it was an issue with the installation, then I'd get that problem with my other devices as well.
This isn't a Pi-hole issue, it's a client issue.
The 2nd DNS was 8.8.8.8 by default.
I had to set the phone to use static IP so I can edit that field.
I changed it to 192.168.1.100 and it didn't help.
I changed it to 192.168.1.2 (pihole's IP), and it didn't help either.
I'm quite lost. The phone doesn't even come up on the logs. As if it has a stealth mode.
What would you suggest to debug this?
Could the phone have some hardcoded way to get ads?
If we ignore the facts that this is a client issue, what's more concerning is that the client doesn't appear on the pihole logs.
I've done endless checks on the DNS and IP address and made sure secondary DNS is set to 192.168.1.2 and IPv6 is disabled on the router.
I restarted the phone, router, pihole... nothing seems to get this phone on the logs.
If the client is not using Pi-hole for DNS, this is the expected result.
There isn't a Pi-hole solution to the phone problem. I would visit a forum for that phone and OS.
I've searched for similar issues, but nothing came up. I'll go to some forums.
The pihole DHCP picks the phone and I even assigned a static IP to it.
But nothing on the logs when I open sites with ads.
I recall having read something about some manufacturer's smartphone models falling back to hardcoded DNS servers if they deem existing user provided DNS settings as invalid.
Your phone seems to exhibit such behaviour.
I suspect you'll find this confirmed if you take a look at the DNS servers reported by sites like www.dnsleaktest.com: They won't list any of your configured upstreams.
To mitigate this, you could try to block outgoing DNS (port 53) for that device on your router, or even better, redirect that to Pi-hole if your router allows.
Are you using Chrome?
That one does fall back on hardcoded DNS servers
How is it when you use Firefox or Opera?
You can try to change Chrome's behaviour: wit ADB
Do you mean something like this? Where the internal IP address is the phone's IP and the external is the Pihole IP?
Actually, it's a native app that I'm using on that dodgy android phone.
On my phone, even if I use chrome app, ads are being blocked.
On my PC I use chrome as well and they are being blocked.
I would switch to Firefox if they had all the chrome extension I'm using.
Maybe, I don't know your router.
If BOTH for Protocol translates to TCP + UDP, that's fine.
Likely, Internal Port should be blank.
You'd have to figure by your router whether Internal IP Address or Source IP would be the correct choice.
You should also make sure you've researched how your router would apply those settings (e.g.to your whole network or just a single device).
ok, I finally found the issue.
Digging in the phone settings there's a specific setting called Private DNS.
By default it is set to Auto, supposedly encrypting the DNS. I had to set it to OFF in order for it to respect my DNS settings.
If you own a Realme phone or some variant of Chinese phone, there you have it.
