DNS wont resolve :(

@RustedBuckett

/etc/dnsmasq.d/01-pihole.conf interface=enp3s0

Am a bit puzzled as from above, Pi-hole is configured to only answer DNS queries on the enp3s0 interface.

@RustedBuckett

[root@localhost ~]# nslookup pi.hole $(hostname -I)
Server: 192.168.122.1
Address: 192.168.122.1#53

** server can't find pi.hole: NXDOMAIN

But from above, you seem to get an answer from the IP on the virbr0 interface.
The answer is not the correct one though:

pi@noads:~ $ nslookup pi.hole $(hostname -I)
Server:         10.0.0.2
Address:        10.0.0.2#53

Name:   pi.hole
Address: 10.0.0.2

Am wondering now, do you have some other DNS resolver running on the side ?

sudo netstat -nltup | grep 'Proto\|:53 \|:67 \|:80 \|:471[1-8] '

nslookup -class=chaos -type=txt version.bind 192.168.1.101

nslookup -class=chaos -type=txt version.bind 192.168.122.1

And does below file contain the pi.hole name with proper IP ?

cat /etc/pihole/local.list

If you want Pi-hole to resolve DNS queries on both the enp3s0 and the virbr0 interface, you can change below Pi-hole setting:

Also for diagnosing, you could try flush the firewall/iptables rules temporally just to be sure its not dropping network packets:

Admin page shows FTL Offline | Unable to start, cannot access dhcp.leases

Below ones seems to do the trick: sudo iptables -F sudo iptables -X sudo iptables -t nat -F sudo iptables -t nat -X sudo iptables -t nat -L -n -v sudo iptables -t mangle -F sudo iptables -t mangle -X sudo iptables -P INPUT ACCEPT sudo iptables -P OUTPUT ACCEPT sudo iptables -P FORWARD ACCEPT Check afterwards with: pi@noads:~ $ sudo iptables -L -n Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source …
