Ubuntu Mate - pihole configuration

[rsivaguru]

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

Expected Behaviour:

Expecting queries to be blocked - still seeing ads on all the clients connected to the internet. Installation seems perfect and web interface using lighttpd seems to come up without issues. But Query log shows only query from 12 hours ago. No recent data. H/w Raspberry Pi - 8GB RAM -128GB SD Card. Unable to nslookup pi.hole getting NXDOMAIN. OS Ubuntu Mate 20.04 LTS

Actual Behaviour:

Pihole configuration looks ok - web interface coming up ok showing active but pihole not blocking any queries. Router DNS entries updated

Debug Token:

Then your clients aren't using Pi-hole anymore.

What does your /etc/resolv.conf look like?

Check your networking as well.

I have configured static ip's as:

eth0 - 10.0.1.60
wlan0 - 10.0.1.61

Should I edit /etc/pihole/setupVars.conf?

Should the raspberry pi - networking connections for both eth0 and wlan0 show the DNS entry to be 10.0.1.60?

Why should Pi-hole be my only DNS server?

Reduced Ad Blocking Capability The main reason you should Pi-hole as your only DNS server is that you will see increased performance in the blocking of ads. If you have two DNS servers (Pi-hole and something else), your network clients may not always query Pi-hole for name resolution. If a query happens to be answered from a non-Pi-hole DNS server, your block lists will not apply (since that DNS server doesn't know about them). All Queries Need To Go Through Pi-hole First Since other DNS se…

Why do you have both eth0 and wlan0 operating at the same time? How do you want your clients to access the Pi-hole? You'll need a single static IP address for the clients to use, and it needs to be accessible all the time.

[rsivaguru]

Do you recommend that I disable the wlan0 from using a static IP? The reason I had 2 static IP configured was to easily remember the IP's and in case if I needed to ssh to the raspberry pi.

I was hoping that the clients connect to eth0 - 10.0.1.60 for pihole and also have a wifi interface up with a static address. However based on your questions, I disabled wifi configuration on the raspberry pi and now have only one network interface up. I also reconfigured pihole by executing pihole -r and it now looks like it is functional and blocking ads.
