+# HowTo: OpenVPN
+
+## Installing OpenVPN Server on Ubuntu 20.04
+
+I used the excellent all-in-one [OpenVPN Install](https://github.com/Nyr/openvpn-install) script to do the heavy lifting for this.  There were a few caveats that weren't immediately apparent, mostly because of my ignorance in setting up OpenVPN.
+
+I also made sure to open UDP port 1194 on the my Router/Modem and forward that port to Phaedrus
+
+Afterwards, I was able to use the `ovpn` file to connect to my LAN
+
+## Specifying a DNS with OpenVPN
+
+After installing OpenVPN on a VM recently I decided I wanted it to use my local Pi-Hole instance as its DNS so I can block ads while connected to the VPN.
+
+It's as easy as specifying the DNS in `/etc/openvpn/server/server.conf`, like so:
+
+```ini
+push "dhcp-option DNS 192.168.0.206"
+```
+
+Then restart openvpn with `sudo systemctl restart openvpn-server@server`
