Trusted Proxy Auth

⚠️ Security-sensitive feature. This mode delegates authentication entirely to your reverse proxy. Misconfiguration can expose your Gateway to unauthorized access. Read this page carefully before enabling.

​

When to Use

• You run OpenClaw behind an identity-aware proxy (Pomerium, Caddy + OAuth, nginx + oauth2-proxy, Traefik + forward auth)
• Your proxy handles all authentication and passes user identity via headers
• You’re in a Kubernetes or container environment where the proxy is the only path to the Gateway
• You’re hitting WebSocket 1008 unauthorized errors because browsers can’t pass tokens in WS payloads

​

When NOT to Use

• If your proxy doesn’t authenticate users (just a TLS terminator or load balancer)
• If there’s any path to the Gateway that bypasses the proxy (firewall holes, internal network access)
• If you’re unsure whether your proxy correctly strips/overwrites forwarded headers
• If you only need personal single-user access (consider Tailscale Serve + loopback for simpler setup)

​

How It Works

1. Your reverse proxy authenticates users (OAuth, OIDC, SAML, etc.)
2. Proxy adds a header with the authenticated user identity (e.g., x-forwarded-user: nick@example.com)
3. OpenClaw checks that the request came from a trusted proxy IP (configured in gateway.trustedProxies)
4. OpenClaw extracts the user identity from the configured header
5. If everything checks out, the request is authorized

​

Control UI Pairing Behavior

• Pairing is no longer the primary gate for Control UI access in this mode.
• Your reverse proxy auth policy and allowUsers become the effective access control.
• Keep gateway ingress locked to trusted proxy IPs only (gateway.trustedProxies + firewall).

​

Configuration

{
  gateway: {
    // Use loopback for same-host proxy setups; use lan/custom for remote proxy hosts
    bind: "loopback",

    // CRITICAL: Only add your proxy's IP(s) here
    trustedProxies: ["10.0.0.1", "172.17.0.1"],

    auth: {
      mode: "trusted-proxy",
      trustedProxy: {
        // Header containing authenticated user identity (required)
        userHeader: "x-forwarded-user",

        // Optional: headers that MUST be present (proxy verification)
        requiredHeaders: ["x-forwarded-proto", "x-forwarded-host"],

        // Optional: restrict to specific users (empty = allow all)
        allowUsers: ["nick@example.com", "admin@company.org"],
      },
    },
  },
}

TLS termination and HSTS

​

Recommended pattern: proxy TLS termination

• Good fit for internet-facing deployments.
• Keeps certificate + HTTP hardening policy in one place.
• OpenClaw can stay on loopback HTTP behind the proxy.

Strict-Transport-Security: max-age=31536000; includeSubDomains

​

Gateway TLS termination

{
  gateway: {
    tls: { enabled: true },
    http: {
      securityHeaders: {
        strictTransportSecurity: "max-age=31536000; includeSubDomains",
      },
    },
  },
}

​

Rollout guidance

• Start with a short max age first (for example max-age=300) while validating traffic.
• Increase to long-lived values (for example max-age=31536000) only after confidence is high.
• Add includeSubDomains only if every subdomain is HTTPS-ready.
• Use preload only if you intentionally meet preload requirements for your full domain set.
• Loopback-only local development does not benefit from HSTS.

Proxy Setup Examples

​

Pomerium

{
  gateway: {
    bind: "lan",
    trustedProxies: ["10.0.0.1"], // Pomerium's IP
    auth: {
      mode: "trusted-proxy",
      trustedProxy: {
        userHeader: "x-pomerium-claim-email",
        requiredHeaders: ["x-pomerium-jwt-assertion"],
      },
    },
  },
}

routes:
  - from: https://openclaw.example.com
    to: http://openclaw-gateway:18789
    policy:
      - allow:
          or:
            - email:
                is: nick@example.com
    pass_identity_headers: true

​

Caddy with OAuth

{
  gateway: {
    bind: "lan",
    trustedProxies: ["127.0.0.1"], // Caddy's IP (if on same host)
    auth: {
      mode: "trusted-proxy",
      trustedProxy: {
        userHeader: "x-forwarded-user",
      },
    },
  },
}

openclaw.example.com {
    authenticate with oauth2_provider
    authorize with policy1

    reverse_proxy openclaw:18789 {
        header_up X-Forwarded-User {http.auth.user.email}
    }
}

​

nginx + oauth2-proxy

{
  gateway: {
    bind: "lan",
    trustedProxies: ["10.0.0.1"], // nginx/oauth2-proxy IP
    auth: {
      mode: "trusted-proxy",
      trustedProxy: {
        userHeader: "x-auth-request-email",
      },
    },
  },
}

location / {
    auth_request /oauth2/auth;
    auth_request_set $user $upstream_http_x_auth_request_email;

    proxy_pass http://openclaw:18789;
    proxy_set_header X-Auth-Request-Email $user;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

​

Traefik with Forward Auth

{
  gateway: {
    bind: "lan",
    trustedProxies: ["172.17.0.1"], // Traefik container IP
    auth: {
      mode: "trusted-proxy",
      trustedProxy: {
        userHeader: "x-forwarded-user",
      },
    },
  },
}

​

Security Checklist

• Proxy is the only path: The Gateway port is firewalled from everything except your proxy
• trustedProxies is minimal: Only your actual proxy IPs, not entire subnets
• Proxy strips headers: Your proxy overwrites (not appends) x-forwarded-* headers from clients
• TLS termination: Your proxy handles TLS; users connect via HTTPS
• allowUsers is set (recommended): Restrict to known users rather than allowing anyone authenticated

​

Security Audit

• Missing trustedProxies configuration
• Missing userHeader configuration
• Empty allowUsers (allows any authenticated user)

​

Troubleshooting

​

”trusted_proxy_untrusted_source”

• Is the proxy IP correct? (Docker container IPs can change)
• Is there a load balancer in front of your proxy?
• Use docker inspect or kubectl get pods -o wide to find actual IPs

​

”trusted_proxy_user_missing”

• Is your proxy configured to pass identity headers?
• Is the header name correct? (case-insensitive, but spelling matters)
• Is the user actually authenticated at the proxy?

​

“trustedproxy_missing_header*”

• Your proxy configuration for those specific headers
• Whether headers are being stripped somewhere in the chain

​

”trusted_proxy_user_not_allowed”

​

WebSocket Still Failing

• Supports WebSocket upgrades (Upgrade: websocket, Connection: upgrade)
• Passes the identity headers on WebSocket upgrade requests (not just HTTP)
• Doesn’t have a separate auth path for WebSocket connections

​

Migration from Token Auth

1. Configure your proxy to authenticate users and pass headers
2. Test the proxy setup independently (curl with headers)
3. Update OpenClaw config with trusted-proxy auth
4. Restart the Gateway
5. Test WebSocket connections from the Control UI
6. Run openclaw security audit and review findings
