Cloudflare Tunnel creates an encrypted connection from your server to Cloudflare's network, hiding your server's real IP address. This protects against DDoS attacks and IP-based targeting.
How It Works
- Install the cloudflared daemon on your server
- Create a tunnel in your Cloudflare dashboard
- Configure the tunnel to forward traffic to your game server
- Players connect to your Cloudflare hostname instead of your IP
Setting Up for Minecraft
Install cloudflared
# Debian/Ubuntu
curl -L --output cloudflared.deb https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-amd64.deb
sudo dpkg -i cloudflared.deb
Create and Configure Tunnel
cloudflared tunnel login
cloudflared tunnel create minecraft-server
Important: TCP vs HTTP
Cloudflare Tunnel primarily supports HTTP/HTTPS. For Minecraft's TCP protocol, you need Cloudflare Spectrum (paid) or an SRV record workaround.
Free alternative: Use a DNS-only setup with Cloudflare proxy disabled (grey cloud) to get DNS management without IP hiding. For full IP hiding with game traffic, consider:
- playit.gg, Free TCP tunneling for game servers
- ngrok, TCP tunnels (limited free tier)
- ZeroTier/Tailscale, VPN-based alternatives for private servers
Limitations for Game Servers
- Cloudflare Tunnel's free tier only proxies HTTP/HTTPS
- Game server traffic (TCP/UDP) requires Cloudflare Spectrum (Enterprise) or alternatives
- Added latency from routing through Cloudflare's network
- Not ideal for latency-sensitive games
When to Use Cloudflare Tunnel
- Protecting web dashboards (Pterodactyl panel, txAdmin)
- API endpoints for bots and dashboards
- Web-based server management tools
When to Use Alternatives
- Direct game traffic (Minecraft, FiveM, Rust): Use a host with built-in DDoS protection
- Private servers: Use ZeroTier or Tailscale
- Public servers: Choose a host with game-grade DDoS protection (like Space-Node)
FAQ
Can I use Cloudflare Tunnel for Minecraft? For the web panel (Pterodactyl), yes. For game traffic, you need Spectrum (paid) or alternatives like playit.gg.
Does Cloudflare Tunnel add latency? Yes, typically 5-20ms depending on your proximity to Cloudflare's edge.
Is Cloudflare Tunnel free? The tunnel itself is free. Proxying TCP/UDP game traffic requires Spectrum (paid).
