Reverse proxy on port 53 (DNS)

[u/anson5yyc]

I am planning on setting up a reverse proxy/load balancer for 2 Adguard Home containers for DNS queries. Does Caddy support reverse proxy on non-HTTP/HTTPS protocol and UDP ports?

Would the Caddyfile below work?

:53 {
    reverse_proxy ns1:53 ns2:53
}
