Pihole + wireless hotspot

Help
1

Hello,
I have raspberry Pi 3+ and I tried installing pihole along a wireless hotspot, but once I do the last step from this tutorial, pihole and internet doesn't work

add in /etc/dnsmasq.conf
interface=wlan0
dhcp-range=192.168.4.2,192.168.4.20,255.255.255.0,24h
ot

^ this part

This is the output of ifconfig

What I'm trying to do is have internet from eth0 and then use pihole to block ads through the wireless hotspot.

What ip are u using for your wlan?
I think I eventually just disabled the dnsmasq and used pihole build in dhcpd

I'll have to check my recipe but I'm not at home

Feel free to pester me tomorrow and I'll look up and post more the most recent recipe I'm using

isee your issue i think since your wlan is at 192.168.42.1
the above dhcp-range should be
dhcp-range=192.168.42.2,192.168.42.20,255.255.255.0,24h

I've changed to dhcp-range=192.168.42.2,192.168.42.20,255.255.255.0,24h but still it doesn't work.

Maybe I'm not clear, I want to have a wireless hotspot with pihole's DHCP and have every client connecting to the hotspot to have ablock from pihole.

Here are my current settings:
$ cat /etc/network/interfaces
auto lo

iface lo inet loopback
iface eth0 inet dhcp

auto eth0
auto wlan0

iface wlan0 inet static
  address 192.168.42.1
  netmask 255.255.255.0
  wireless-power off

up iptables-restore < /etc/iptables.ipv4.nat

$ cat /etc/dnsmasq.conf
interface=wlan0
dhcp-range=192.168.42.2,192.168.42.20,255.255.255.0,24h

at the end of /etc/dhcpcd.conf I have this:
interface wlan0
static ip_address=192.168.42.1/24
static routers=192.168.42.1
static domain_name_servers=127.0.0.1

$ cat /etc/resolv.conf
nameserver 127.0.0.1
search home
