Thanks @jakubhajek My idea is to perform TLS termination on backend services (which is a web application) and have an end to end encryption. I have opened an issue on GitHub. Each of the VMs is running traefik to serve various websites. Traefik will terminate the SSL connections (meaning that it will send decrypted data to the services). More information in the dedicated server load balancing section. Is there any important aspect that I am missing? I will do that shortly. I had to disable TLS entirely and use the special HostSNI(*) rule below to allow straight pass throughts.

That association happens with the tls.certResolver key, as seen below: Make that change, and then deploy the updated IngressRoute configuration. In this context, specifying a namespace when referring to the resource does not make any sense, and will be ignored. Register the TLSOption kind in the Kubernetes cluster before creating TLSOption objects Since it is used by default on IngressRoute and IngressRouteTCP objects, there never is a need to actually reference it. It works fine forwarding HTTP connections to the appropriate backends. 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.

The polished configuration options ensure that configuring Traefik is always achieved the same way whether expressed with TOML, YAML, labels, or keys, and the revamped documentation includes examples for every syntax. I have experimented a bit with this. We do by creating a TLSStore configuration and setting the defaultCertificate key to the secret that contains the certificate. When you have certificates that come from a provider other than Let's Encrypt (either self-signed, from an internal CA, or from another commercial CA), you can apply these certificates manually and instruct Traefik to use them.
