+        traefik.tcp.routers.dumbproxy.rule: HostSNI(`<your-domain>`)

+        traefik.tcp.services.dumbproxy.loadbalancer.proxyProtocol.version: 2
+```
+
+dumbproxy service should be run in plaintext mode as TLS is handled on Traefik side. So options would be just `-bind-address=:8080 -proxyproto` and probably something for authorization. This recipe is explained in [Wiki](https://github.com/SenseUnit/dumbproxy/wiki/Docker-Compose-Deployment-behind-Traefik-Reverse-Proxy) with more details and configuration files provided for context.

 ## Using HTTP-over-TLS proxy
 
 It's quite trivial to set up program which supports proxies to use dumbproxy in plain HTTP mode. However, using HTTP proxy over TLS connection with browsers is little bit tricky. Note that TLS must be enabled (`-cert` and `-key` options or `-autocert` option) for this to work.
