Can't resolve dns lookups on my Pi from LAN devices

[deHakkelaar]

@Lobster

pi@raspberrypi:~ $ nslookup -type=txt -class=chaos version.bind $(hostname -I) ;; connection timed out; no servers could be reached

Whats output for below three?

pi@noads:~ $ ip addr show eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether b8:27:eb:68:35:17 brd ff:ff:ff:ff:ff:ff
    inet 10.0.0.2/24 brd 10.0.0.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::2113:33ca:4a85:5fb/64 scope link

pi@noads:~ $ sudo traceroute -n 8.8.8.8 | tail -1

You can run last one without the "| tail -1" bit to see where route breaks.

And try flush iptables for diagnosing:

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 …

EDIT: ow the upstream servers you configured:

pi@noads:~ $ grep PIHOLE_DNS_ /etc/pihole/setupVars.conf
PIHOLE_DNS_1=62.58.153.220#53
PIHOLE_DNS_2=62.58.48.30#53

Can you do a nslookup against them too to see if they respond ?
