Cloudflare Spectrum TCP & UDP DDoS Protection: Complete Setup Guide for FiveM & Game Ports
Traditional web-only CDN proxies only protect HTTP and HTTPS on ports 80 and 443. For game servers, voice nodes, custom database replication ports, and TCP/UDP socket services, your origin IP address is frequently exposed to devastating multi-gigabit denial-of-service (DDoS) attacks. Cloudflare Spectrum bridges this gap by extending Cloudflare's massive 300+ Tbps global Anycast network to any non-HTTP protocol.
How Cloudflare Spectrum Works on Altivora
- Origin IP Cloaking: Your backend server IP is completely hidden behind Cloudflare's Anycast proxy IP addresses distributed across 330+ global datacenters.
- Layer 4 & Layer 7 Scrubbing: UDP reflection/amplification, SYN floods, ACK floods, and custom application-layer protocol exploits are filtered at the edge within nanoseconds.
- Proxy Protocol v1 & v2 Support: Seamlessly pass through the authentic player / client real IP address to your FiveM or Minecraft server logs and ban managers.
- Traffic Allocation Plans: Choose from 2 TB up to 9 TB of clean, protected monthly bandwidth with 1 to 10 protected dedicated port assignments.
Step-by-Step Proxy Protocol Integration for FiveM
To enable real IP preservation behind Cloudflare Spectrum on your FiveM server:
# In your server.cfg file:
set sv_proxyProtocol 2
set sv_proxyProtocolIPs "103.21.244.0/22 103.22.200.0/22 103.31.4.0/22 104.16.0.0/13 104.24.0.0/14 108.162.192.0/18 131.0.72.0/22 141.101.64.0/18 162.158.0.0/15 172.64.0.0/13 173.245.48.0/20 188.114.96.0/20 190.93.240.0/20 197.234.240.0/22 198.41.128.0/17"
endpoint_add_tcp "0.0.0.0:30120"
endpoint_add_udp "0.0.0.0:30120"
With this configuration, your origin server is 100% immune to direct attacks, and player bans function accurately based on real user IP addresses.
