Potential additional instruction for PiHole + OpenVPN tutorial


I installed PiHole and OpenVPN on my Raspberry following the tutorial on https://docs.pi-hole.net/guides/vpn/firewall/. Unfortunately, after numerous attempts to meticulously follow the tutorial, my setup did not work.

Only until I added the following line to my iptables setup, I got it working:

iptables -t nat -A POSTROUTING -s -o eth0 -j SNAT --to-source

Is this maybe an omission in the tutorial and should this be added?
