My Pi hole is not blocking ads

jfb · July 18, 2019, 8:28pm

Please confirm that this command was run from a connected client, and not from the Pi terminal. If from a client, what OS does the client run?

The output you provided indicates that the request for that domain did not go to Pi-Hole. The following domains should have been requested:

* signaler-pa.clients6.google.com
* www.cnx-software.com
* pagead2.googlesyndication.com
* z-na.amazon-adsystem.com
* fonts.gstatic.com
* quantcast.mgr.consensu.org

and the tail of the pihole log should have looked something like this:

Your pihole log shows none of the requests for the domains on that website - the only requests shown in your log are from the Pi itself (127.0.0.1). The DNS traffic from that client did not go through Pi-Hole.

manohar_basavaraju · July 18, 2019, 8:35pm

Then how do I make it go through pihole? Pls guide me in setting up with correct DNS server pls

jfb · July 18, 2019, 9:19pm

Let's start with a single client and get that working on Pi-Hole.

I assume you have tried to set the DNS settings on your router and that has not worked.

What clients do you have - do you have a PC?

manohar_basavaraju · July 19, 2019, 7:04pm

Yes I do have a PC with Windows. I have set my router as other provider to turn off the DHCP from my provider. After that I enabled the DHCP server on Raspberry pi hole and chose the cloud DNS as upload DNS server.
I don't know what am I doing wrong. It's really frustrating. Should I post the screen shots of my pi hole DNS settings here for correction?

jfb · July 19, 2019, 9:47pm

What is the output of ipconfig /all from the PC terminal?

jfb · July 19, 2019, 10:41pm

2 posts were split to a new topic: Ads not blocked on Windows client

manohar_basavaraju · July 19, 2019, 10:48pm

Hi, can you pls post the DNS server settings on pihole for me pls. I don't know what I am doing wrong only some ads are getting blocked not all.
Here is the screenshot of my settings.
Correct me what u am doing wrong. Thanks

jfb · July 19, 2019, 10:51pm

This isn't the information we need to help you solve this problem. We need this:

manohar_basavaraju · July 19, 2019, 11:19pm

It's 01:15 in the midnight. I am really very tired from work and typing from bed. Can I give you the output of this tomorrow? May be in 7 hrs from now?
Thanks

On the PC, manually map the DNS to the IPv4 address of the Pi, and disable IPv6. This will eliminate IPv6 and the router as potential sources of the problem.

manohar_basavaraju · July 20, 2019, 8:38pm

I didn't get you. What exactly do you want me to do? If I disable ipv6 on pc will it disable on pihole ?
What are the DNS settings I should choose in pihole?

jfb · July 21, 2019, 12:47am

Change the DNS settings on the PC to manually point to Pi-Hole. If you do not know how to do it, then do a web search and you will find many videos and instructions.

No.

Don't change anything in Pi-Hole. As noted in two previous replies, this is not a Pi-Hole configuration problem.

manohar_basavaraju · July 21, 2019, 8:05am

But i do see ads on my mobile. Should i also change the DNS settings in my Mobile ?

DanSchaper · July 21, 2019, 4:00pm

Do you want Pi-hole to block ads on your mobile?

jfb · July 21, 2019, 8:06pm

Get your PC working, then will figure out where the problem lies.

codinghorror · July 22, 2019, 1:50am

One thing worth mentioning for future reference, I had devices looking for IPv6 DNS which, oddly enough, on my ISP provided router has a different set of DNS config pages. That was annoying.. I noticed it on iOS devices which tend to prefer IPv6 in a big way.

manohar_basavaraju · July 22, 2019, 7:50pm

Yes. I thought pi hole blocks adds network wide. Have I misunderstood here?

manohar_basavaraju · July 22, 2019, 7:51pm

I still didn't get the logic what you are trying to explain me...

DanSchaper · July 22, 2019, 7:57pm

You have to tell the devices to use Pi-hole. It can not intercept and replace.

I think you need to spend some time reading https://docs.pi-hole.net and see how it works, how to install it and how to configure your clients and network to use Pi-hole. Until you understand the basics of how things work then any troubleshooting we do will be of little use.
