I install Wireguard + pi-hole on VPS Server (Ubuntu 20.04 LTS)
Connect both Wireguard and Pi-hole
But the issue is Ad's are not blocking in My Client System (Ubuntu 18.04 LTS)
I Test on My Android Device it's work well
But in My system, it does not Block the Ad's VPN only working - I use Pi-hole IP as DNS server in Wireguard
No issue on My Pi-Hole installed server
issue only My cliient server having Ubuntu 18.04
Run this on My Client server
$ grep -v '#\|^$' -R /etc/dnsmasq.*
/etc/dnsmasq.d/network-manager:bind-interface
After Testing with other devices (wireless) it's work well - Tested on My windows 10 system with wireless connection
it does not work in Wired connection
Hello, in your VPS with Ubuntu 20, the file /etc/resolv.conf contain: nameserver VPSprivateIP ?
cat /etc/resolv.conf
# Generated by dhcpcd from eth0.dhcp, wg0.dhcp
# /etc/resolv.conf.head can replace this line
nameserver 1.1.1.1
nameserver 1.0.0.1
# /etc/resolv.conf.tail can replace this line
Fixed
