Remote access with Caddy, Duckdns vs Tailscale for security?

[TheDreadPirate]

I use Nginx, so definitely not a Caddy expert. A cursory read of Caddy's docs, and the DuckDNS module git, doesn't make clear what the "right" or best way is to update Caddy when using a DNS module. You're probably better served by asking on the Caddy forum.
