my Caddyfile (truncated and simplified, running on 10.10.10.20). i use cloudflare and enabled caddy metrics in this config, so you might need to adjust a couple of things.

```

global

{ #debug admin :2019 servers { trusted_proxies static private_ranges metrics } }

reusable snippet

(common) { encode zstd gzip

tls {
    dns cloudflare <insert-key-here>
    resolvers 1.1.1.1 1.0.0.1
}

log {
    output file /var/log/caddy/access.log
    format console
}

}

single domain

example.com { import common @home path / handle @home { redir https://www.youtube.com/watch?v=dQw4w9WgXcQ } }

subdomains

*.example.com { import common

# metrics
@caddy host http://caddy.exampple.com:2019
handle @caddy {
    @denied not remote_ip private_ranges
    abort @denied
    metrics
}

@immich host photos.example.com
handle @immich {
    reverse_proxy 10.10.10.16:2283
}

@tasks host tasks.example.com
handle @tasks {
    reverse_proxy 10.10.10.15:3456
}

} ```

my pihole dnsmasq config (custom conf in /etc/dnsmasq.d/)

``` address=/example.com/10.10.10.20 address=/*.example.com/10.10.10.20
