OpenVPN + Pi-Hole

[Jacopx]

Buonasera a tutti!

I have just build my first pfSense and it's working perfectly. I have also made everything for the OpenVPN connection. It's work but I can't use the DNS that I want…

In my LAN I have my pfSense box that have, like DNS:
127.0.0.1
172.16.0.2 (My DNS with Pi-Hole)
192.168.0.1 (DNS of WAN)

What I want is to using from the outside my Pi-Hole. Which is the best configuration, that allows me to keep my client routing to the Raspberry for the querying?

I have already try to add the classic:
Code: [Select]
push "dhcp-option DNS 172.16.0.2"
in the serve VPN config but It's not work…

The result of ping or dig to my raspberry are corrects and they're work. But If I try to change manually the DNS server my VPN goes down...

Thanks!  ;)
