+# Exemple
+## Behind another proxy service (ex: clouflare)
+
+You need to configure your Traefik to trust Forwarded headers by your front proxy
+In the example we use another instance of traefik with the container named cloudflare to simulate a front proxy
+
+The "internal" Traefik instance is configured to trust the cloudflare forward headers
+This helps Traefik choose the right IP of the client: see https://doc.traefik.io/traefik/routing/entrypoints/#forwarded-headers
+```yaml
+  - "--entrypoints.web.forwardedheaders.trustedips=172.21.0.5"
+```
+
+We configure the middleware to trust as well the IP:
+```yaml
+    - "traefik.http.middlewares.crowdsec1.plugin.bouncer.forwardedheaderstrustedips=172.21.0.5"
+```
+
+To play the demo environment run:
+```bash
+make run_behindproxy
+```
