Product Description

Cloudflare Tunnels provide a secure remote access solution for OpenClaw, allowing access to OpenClaw instances via custom domains without opening router ports. Combined with Cloudflare Zero Trust Access, it enables secure remote management without exposing the Gateway to the public internet, significantly reducing OpenClaw's attack surface.

Core Features

Cloudflare Tunnels

  • Create secure outbound connections from local to Cloudflare's edge network
  • No need to open router ports or expose public IPs
  • Access OpenClaw via custom domains
  • Cloudflare edge network routes traffic back to local machines

Zero Trust Access

  • Protect OpenClaw Gateway WebUI with Cloudflare Tunnel
  • DNS switching supports custom hostnames
  • Authentication and access control policies
  • Application-level security protection

Workers VPC

  • Access self-hosted OpenClaw via Cloudflare Workers VPC
  • Complete network isolation and security settings
  • Supports OpenClaw deployment on VPS

Security Advantages

  • Zero Port Exposure: No need to open any ports on the firewall
  • No Direct Internet Exposure: OpenClaw is not directly exposed to the public internet
  • Low Attack Surface: Significantly reduces the attack surface
  • Recommended as one of the "most secure practical deployment solutions"

Security Risks to Note

  • Reverse Proxy Misconfiguration: Misconfigurations when using reverse proxies or Cloudflare Tunnels can make all connections appear to come from 127.0.0.1
  • localhost Trust Bypass: Misconfigurations can bypass OpenClaw's localhost trust model
  • CVE-2026-29613: Webhook authentication bypass vulnerability (when Gateway is behind a reverse proxy)
  • Proper configuration is required to ensure security value is not negated

Relationship with OpenClaw Ecosystem

Cloudflare Tunnels have become one of the standard components for secure OpenClaw deployments, alongside Tailscale, as one of the most recommended remote access solutions. In the context of 93.4% of 42,000+ exposed instances having authentication bypass vulnerabilities, using Cloudflare Tunnels to protect OpenClaw access is no longer optional but a fundamental requirement for secure deployment.
