DDoS Protection for Game Servers
What is a DDoS Attack?
A Distributed Denial of Service (DDoS) attack floods your server with so much traffic that legitimate players can no longer connect.
Common Attack Types
| Type | Description | Target |
|---|---|---|
| UDP Flood | Massive UDP packets | Game server ports |
| SYN Flood | Half-open TCP connections | Web panels |
| Amplification | DNS/NTP amplification | Bandwidth |
| Application Layer | Login spam, query flood | Application |
Why Are Game Servers Targeted?
- Competition: Other server operators
- Frustrated players: After a ban or wipe
- Extortion: "Pay up or we'll keep DDoSing"
- Boredom: Script kiddies testing tools
Protection Measures
What Your Host Should Do
- Network-level filtering: Traffic is filtered before reaching the server
- Anycast: Traffic is distributed across multiple locations
- Rate limiting: Too many requests from one IP = block
- Blackholing: During extreme attacks, the IP is temporarily null-routed
What You Can Do
- Don't make your server IP public: Use a domain or proxy
- Disable query if not needed
- Firewall rules: Only open necessary ports
- VPN for admin access: SSH not on the default port
