In this guide, I explore using #Caddy as a reverse proxy with Let's Encrypt DNS challenges and #CrowdSec protection via a CrowdSec bouncer. Additionally, CrowdSec will be configured in a multi-server configuration with #OPNsense which has some benefits as mentioned in the guide.

In order to support DNS challenges and CrowdSec, you will have to build a custom Caddy executable. Using Caddy's build tool called xcaddy makes the process easier to accomplish.

Because of the manual build process, this guide will be more involved than simply setting up a basic Caddy web server/reverse proxy.
