## How do I use Pi-hole with PiVPN?
You can safely install PiVPN on the same Raspberry Pi as your Pi-hole install, and point your VPN clients to the IP of your Pi-hole so they get ad blocking, etc.
Note that if you install PiVPN after Pi-hole, your existing Pi-hole installation will be detected and the script will ask if you want to use is as the DNS for the VPN, so you won't need to go through all these steps.

1. Create a new file `sudo nano /etc/dnsmasq.d/02-pivpn.conf`

## How to resolve local hostnames?
All you have to do is to use your router as DNS Server instead of using other public DNS providers.
If you have already a working installation of OpenVPN, all you need to do is to edit `/etc/openvpn/server.conf` and replace every `push "dhcp-option DNS [...]"` line, with A SINGLE `push "dhcp-option DNS 192.168.23.1"` (assuming 192.168.23.1 is your gateway IP). Then restart the openvpn service: `sudo systemcl restart openvpn`.

Alternatively you can change `/etc/hosts` file and add `<IPAddress> <hostname>`
