In the section above, Traefik Proxy handles TLS, But there are scenarios where your application handles it instead. or referencing TLS options in the IngressRoute / IngressRouteTCP objects. This means that no proxy protocol needed, but it also means that in the future I will have to always test the setup 4 times, over IPv4/IPv6 and over HTTP/2/3, as in each scenario the packages will take a different route. Changing the config, parameters and/or mode of access in my humble opinion defeats the purpose. TCP services are not HTTP, so netcat is the right tool to test it or openssl with piping message to session, see the examples above how I tested Whoami application. Why are physically impossible and logically impossible concepts considered separate in terms of probability? The passthrough configuration needs a TCP route instead of an HTTP route.
