+### TLS communication between Traefik and backend pods
+
+Traefik automatically requests endpoint information based on the service provided in the ingress spec.
+Although traefik will connect directly to the endpoints (pods), it still checks the service port to see if TLS communication is required.
+If the service port defined in the ingress spec is 443, then the backend communication protocol is assumed to be TLS, and will connect via TLS automatically.
+
+!!! note
+    Please note that by enabling TLS communication between traefik and your pods, you will have to have trusted certificates that have the proper trust chain and IP subject name. 
+    If this is not an option, you may need to skip TLS certificate verification.
+    See the [InsecureSkipVerify](configuration/commons/#main-section) setting for more details.
