Triple-Layer DDoS Protection Pipeline
Every packet traverses five defense stages before reaching your RAN Online server. Three independent filtering layers provide true defense-in-depth with fault isolation.
Cloudflare Spectrum
Player traffic hits Cloudflare's global Anycast network. L3/L4 attacks absorbed across 300+ PoPs before reaching origin.
Channel Relay
Clean traffic forwarded through 7 dedicated relay endpoints — one per game channel port.
OVH VAC Clusters
Two isolated dedicated server clusters perform hardware-level volumetric scrubbing with fault isolation.
XDP Scrubbing
Kernel-level packet filtering validates and scrubs every packet at wire speed before forwarding.
Backend Delivery
Verified traffic arrives at multi-IP Windows backend via Proxy Protocol v1 with real player IPs.
Traffic Flow & Network Topology
Full end-to-end view of how player traffic flows from the public internet through triple-layer defense to your RAN Online backend across 7 game channels.
Network Architecture
Live InfrastructureInternet / Players

Cloudflare Spectrum
Single public entry IP distributes traffic across 7 forwarded channels with L4 DDoS protection at the global edge.
OVH VAC Clusters
Two dedicated clusters separate the primary 6-port group from the isolated port 5511 route for fault isolation.
XDP Scrubbing
Kernel-level packet filtering validates and scrubs all traffic at wire speed, dropping malformed packets instantly.
Proxy Protocol v1
Original client connection metadata preserved through every hop, delivering real player IPs to the backend.
Why Choose HolicNode for RAN Online DDoS Protection
Purpose-built infrastructure for MMORPG workloads. Every feature is designed to keep your players connected and your server online.
7-Port Channel Protection
Full DDoS protection across all 7 RAN Online service ports. Each channel has dedicated Cloudflare Spectrum relay endpoints and XDP scrubbing rules optimized for game traffic patterns.
Dual OVH VAC Clusters
Traffic isolated across two independent OVH VAC dedicated server clusters. An attack on one cluster cannot impact the other, ensuring partial availability during sophisticated multi-vector campaigns.
XDP Kernel-Level Scrubbing
eXpress Data Path filtering processes packets at the earliest point in the Linux kernel stack. Malicious packets dropped at wire speed with sub-millisecond latency before consuming server resources.
Real Player IP Preservation
Proxy Protocol v1 passes original client IPs through all three protection layers. Ban lists, IP-based access control, GeoIP restrictions, and analytics work without modifications.
Always-On, Zero-Delay
Protection is active on every packet at all times. No detection delay or activation period. Attacks are filtered from the first malicious packet across all three layers simultaneously.
1 Tbps+ Mitigation
Combined Cloudflare, OVH VAC, and XDP infrastructure absorbs the largest volumetric attacks. UDP floods, SYN floods, amplification attacks, and connection exhaustion all mitigated.
