Expected Behaviour:
Followed Redirecting... to install openvpn on a raspbian which already has a running pihole+unbound.
The only difference between my steps with the docs is I had a pihole+unbound first, then install openvpn later. I didn't choose tun0 interface to configure pihole as it was already running fine on eth0. I assumed to change the listen interfaces to all on pihole dashboard will work.
Actual Behaviour:
no matter I push which DNS server in OpenVPN configuration file, on OpenVPN client log, the DNS always shows 127.0.0.1. (I think it may relate to pihole use 127.0.0.1#5353 to query unbound)
After connect OpenVPN, the intranet and Internet both works via IP addresses, no DNS resolving.
Debug Token:
N/A
Not sure what I can do to make pihole, unbound and openvpn work together. Thanks.
Thanks a lot @RamSet .
I installed and configured OpenVPN on top of pihole and unbound this time again. It works without any issue now.
I believe systemctl restart openvpn-server@server did the trick.
The only difference last time from today is I used service openvpn restart instead.
