I am not very familiar with Linux, as I have predominantly been involved with everything Microsoft for the majority of my IT life, but I am just looking at the possibility of implementing a pair of Ubuntu DNS Servers that will perform external lookups using Cloudflare's DNS over TLS.
I have read some articles saying that you can use:
- Bind9 with stunnel
- nginx as a TLS proxy
However, I am not sure of the best and easiest method and just wondered if anyone had an opinion on what I should be using and if there is any documentation on how to setup and configure.
