Comment utiliser Cloudflare pour les serveurs FiveM

Is your server getting attacked? In this guide, we’ll walk you through the process of integrating Cloudflare with your CinqM server. Using Cloudflare can enhance your server’s performance, security, and reliability, ensuring a smooth gaming experience for your players.

1. Introduction: Cloudflare & FiveM

CinqM is a modification framework for Grand Theft Auto V that allows you to create customized multiplayer servers. Running a FiveM server requires reliable performance and robust security to handle multiple players and protect against threats like DDoS attacks.

Cloudflare is a leading content delivery network (CDN) and web security service that offers features such as DNS management, SSL/TLS encryption, DDoS protection, and performance optimization. Integrating Cloudflare with your FiveM server can provide enhanced security, reduced latency, and improved overall performance.

2. Prerequisites

Avant de commencer, assurez-vous de disposer des éléments suivants :

• A FiveM Server: Ensure your FiveM server is up and running. If you don’t have one, you can set it up using our guide.
• Nom de domaine: A registered domain name that you own. You can purchase one from registrars like Namecheap, GoDaddy, or others.
• Access to Your Domain’s DNS Settings: Necessary for updating DNS records.
• Cloudflare Account: If you don’t have one, you’ll create it in the next steps (step 3).

3. Setting Up a Cloudflare Account

1. Sign Up for Cloudflare
   • Visit Cloudflare’s website and click on the “Sign Up” button.
   • Enter your email address and create a strong password.
   • Confirm your email address by clicking the verification link sent to your inbox.
2. Add Your Domain to Cloudflare
   • After logging in, click on “Add a Site”.
   • Enter your domain name (e.g., yourdomain.com) and click “Add Site”.
   • Cloudflare will scan your existing DNS records. This process may take a few seconds.
3. Choose a Cloudflare Plan
   • Select a plan that fits your needs. For most FiveM servers, the Gratuit plan offers sufficient features. Click “Confirm” pour procéder.
4. Review DNS Records
   • Cloudflare will display the DNS records it found. Ensure that all necessary records for your domain are present.
   • You can add or modify records as needed later in the DNS settings.
5. Update Your Domain’s Nameservers
   • Cloudflare will provide two nameservers. Log in to your domain registrar’s website and update your domain’s nameservers to the ones provided by Cloudflare.
   • This change might take up to 24 hours to propagate, but it usually happens much faster.

4. Configuring DNS for Your FiveM Server

To direct your domain to your FiveM server, you need to set up the appropriate DNS records.

1. Access Cloudflare DNS Settings
   • Log in to your Cloudflare account.
   • Select your domain from the dashboard.
   • Accédez au “DNS” tab.
2. Add an A Record for Your Server
   • Click on “Add Record”.
   • Taper: Select A from the dropdown.
   • Nom: Enter the subdomain you want to use (e.g., fivem pour fivem.yourdomain.com).
   • IPv4 Address: Enter your FiveM server’s IP address.
   • TTL: Leave it as Auto.
   • Proxy Status: Toggle “Proxy status” à “Proxied” (orange cloud) to enable Cloudflare’s features.
   • Cliquez “Save”.
3. Verify the DNS
   • Utilisez des outils comme DNS Checker to ensure your DNS changes have propagated globally.

5. Setting Up SSL/TLS for Secure Connections

Securing your FiveM server with SSL/TLS ensures encrypted communication between your server and players.

1. Navigate to SSL/TLS Settings
   • In your Cloudflare dashboard, select your domain.
   • Cliquez sur le “SSL/TLS” tab.
2. Choose SSL Mode
   • Flexible: Encrypts traffic between the user and Cloudflare. Not recommended for servers requiring end-to-end encryption.
   • Complet: Encrypts traffic between the user and Cloudflare, and Cloudflare and your server. Requires an SSL certificate on your server.
   • Full (Strict): Same as Full but verifies the SSL certificate on your server is valid.
   For FiveM servers, Complet ou Full (Strict) is recommended if your server supports SSL.
3. Install an SSL Certificate on Your Server (If Needed)
   • Obtain an SSL certificate from a trusted Certificate Authority (CA) or use Cloudflare’s Origin CA certificates.
   • Follow FiveM’s documentation or relevant guides to install the SSL certificate on your server.
4. Enable Always Use HTTPS
   • Dans le SSL/TLS settings, enable “Always Use HTTPS” to ensure all connections use HTTPS.

6. Enhancing Security with Cloudflare Features

Cloudflare offers several security features to protect your FiveM server from various threats.

DDoS (Distributed Denial of Service) attacks can overwhelm your server with traffic, causing downtime.

1. Automatic Protection
   • Cloudflare automatically provides DDoS protection for all proxied traffic. Ensure that your FiveM server’s DNS record is set to Proxied (orange cloud).
2. Rate Limiting
   • Accédez au “Firewall” tab.
   • Click on “Tools” et puis “Rate Limiting”.
   • Set up rules to limit the number of requests from a single IP, helping mitigate DDoS attacks.

Firewall rules allow you to control the traffic that reaches your server.

1. Access Firewall Settings
   • In the Cloudflare dashboard, go to the “WAF” tab.
   • Click on “Firewall Rules”.
2. Create a New Firewall Rule
   • Cliquez “Create a Firewall Rule”.
   • Nom your rule (e.g., Block Malicious Traffic).
   • Define Criteria: Set conditions based on IP addresses, countries, or other attributes to allow or block traffic.
     • Example: Block traffic from specific countries known for malicious activity.
   • Action: Choose “Block”, “Challenge”, ou “Allow” based on your needs.
   • Cliquez “Deploy” to activate the rule.
3. Review and Adjust Rules
   • Regularly monitor your firewall rules and adjust them as necessary to balance security and accessibility.
