+## Forward Proxy (HTTP CONNECT)
+
+Some CASBs (e.g. Netskope or Zscaler in proxy-chaining mode) reach upstream
+proxies via an HTTP `CONNECT` tunnel instead of a standard HTTPS request. Enable
+the firewall's CONNECT listener with `forwardProxy.enabled` (requires image
+≥ 1.1.275).
+
+Because `CONNECT` is a raw TCP tunnel, it cannot pass through a Layer-7 Ingress
+(nginx, Traefik, AWS ALB) — those terminate TLS and parse HTTP. Expose it with a
+**Layer-4 (TCP passthrough) load balancer** by setting
+`forwardProxy.service.enabled=true`, which creates a dedicated Service for the
+CONNECT port. Your existing Ingress/Service keeps serving normal HTTPS traffic.
+
+```yaml
+forwardProxy:
+  enabled: true
+  service:
+    enabled: true
+    type: LoadBalancer   # must be L4 (TCP passthrough), not an L7 ingress
+```
+
+See [`examples/forward-proxy.yaml`](examples/forward-proxy.yaml) for a complete
+example.
