+!!! important "Cross-provider namespace"
+
+    As Kubernetes also has its own notion of namespace, one should not confuse the kubernetes namespace of a resource
+    (in the reference to the middleware) with the [provider namespace](../../providers/overview.md#provider-namespace),
+    when the definition of the TCP middleware comes from another provider.
+    In this context, specifying a namespace when referring to the resource does not make any sense, and will be ignored.
+    Additionally, when you want to reference a MiddlewareTCP from the CRD Provider,
+    you have to append the namespace of the resource in the resource-name as Traefik appends the namespace internally automatically.
+
+More information about available TCP middlewares in the dedicated [middlewares section](../../middlewares/tcp/overview.md).
