Pi-hole not working for all devices

[murtigujar]

Please follow the below template, it will help us to help you!

Expected Behaviour:

pihole should work for all the devices

Actual Behaviour:

I have installed pi-hole on raspberry pi3 b+ (raspbian os), connected to my router via eth0.
Ads are being blocked if i browse on the rapsberry pi
However when i connect my mac on wifi, ads are not blocked
I have changed the /etc/resolv.conf on mac to have my pi-hole ip

$ cat /etc/resolv.conf
nameserver 192.168.1.24

$ nslookup pi.hole
Server: 192.168.1.24
Address: 192.168.1.24#53

Name: pi.hole
Address: 192.168.1.24

I have changed the DNS server on my router to point to pi-hole.
Interface listening behavior is set to Listen on all interfaces, permit all origins
Upstream DNS Servers configuration checked for OpenDNS.

Btw I want the router to manage DHCP rather than pi-hole

Any help appreciated, thanks.

resolv.conf isn't actually used or consulted in macOS for name resolution.

You do not need to manually set each device to use Pi-hole. It's common to configure your router to hand out Pi-hole as a DHCP option. That said, there are three methods to get your devices to use Pi-hole. Have you read through this documentation?

How do I configure my devices to use Pi-hole as their DNS server?

Three methods Generally, there are three different methods that will enable devices on your network to be protected by Pi-hole. 1. Define Pi-hole's IP address as the only DNS entry in the router Rationale Only is italicized here for a reason: Pi-hole needs to be the only DNS server because it intercepts queries and decides whether or not they should be blocked. If you have other DNS servers configured, you may be sent to the correct domain, bypassing Pi-hole completely. Because of this, we…

Use the network preference pane on your Mac to select/check DNS. Network > advanced > DNS. This should show the IP address of your router, since this is providing DHCP services. The router is pointed to the Pi-Hole, so this is correct. Sometimes the router will pass the DNS address of the Pi-Hole and you will see the DNS of the Pi-Hole here instead. That is also acceptable.

Macs can hang onto old DNS settings for a while. To flush the DNS settings on your mac, run this command from the Mac terminal:

sudo killall -HUP mDNSResponder; sleep 2; echo macOS DNS Cache Reset | say

Hi Jacob,
Yes I went through the documentation. I want to go for method 1. I did configure the pi-hole IP on the router, but i just checked again and it seems it is NOT the only DNS, though it is the first one.
|DNS1: |192.168.1.24|
|DNS2: |75.75.75.75|
|DNS3: |75.75.76.76|

Will this not work, as the documentation says the only DNS should be pi-hole?

Thanks jfb, I did the change in the Mac settings, previously it was showing 3 DNS. Now I changed it to only the pi-hole IP. Also flushed using the cmd you provided, but i guess the main problem is still there. As i have mentioned in my other reply, the router still shows 3 DNS. I am trying to figure out if there is any way to force only the pi-hole as DNS on my router (Linksys E900).
