+# Exemple
+## Using Trusted IP (ex: LAN OR VPN) that won't get filtered by crowdsec
+
+You need to configure your Traefik to trust Forwarded headers by your front proxy
+In the example we use a whoami container protected by crowdsec, and we ban our IP before allowing using TrustedIPs
+
+If you are using another proxy in front, you need to add its IP in the trusted IP for the forwarded headers.
+This helps Traefik choose the right IP of the client: see https://doc.traefik.io/traefik/routing/entrypoints/#forwarded-headers
+The "internal" Traefik instance is configured to trust the forward headers
+```yaml
+  - "--entrypoints.web.forwardedheaders.trustedips=172.21.0.5"
+```
+
+We configure the middleware to trust as well as the IP of the intermediate proxy if needed:
+```yaml
+    - "traefik.http.middlewares.crowdsec.plugin.bouncer.forwardedheaderstrustedips=172.21.0.5"
+```
+
+Add your IP to the ban list
+```bash
+docker exec crowdsec cscli decisions add --ip 10.0.10.30 -d 10m
+```
+You should get a 403 on http://localhost/foo
+
+> Replace *10.0.10.30* by your IP
+
+Add the IPs that will not be filtered by the plugin
+```yaml
+    - "traefik.http.middlewares.crowdsec.plugin.bouncer.clientTrustedips=10.0.10.30/32"
+```
+
+> Replace *10.0.10.30/32* by your IP or IP range, so it's not getting checked against ban cache of crowdsec
+
+You should get a 200 on http://localhost/foo even if you are on the ban cache
+
+To play the demo environment run:
+```bash
+make run_trustedips
+```
