How to protect against DDOS ?
Hi! To launch your public gameserver on your home network, start by setting up the server properly. For protection against DDOS attacks, consider using a reliable hosting provider with built-in safeguards, enabling rate limiting, and monitoring traffic regularly. Make sure to secure your server with strong passwords and keep software updated.
For a server, sending traffic upstream usually takes priority over receiving traffic. Even with strong download speeds, good upload performance is essential. Avoid relying on your home connection. If someone attempts to disable your server via a DDOS attack, your local network will also be impacted. Use an external server so your own link remains functional. There’s limited defense against DDOS except by having more bandwidth, processing power, and multiple sites. A common approach is to mask your server with services like Cloudflare. Consider why an attacker might aim for you—if it’s a local site with a limited IP range, the threat level is low.
I need to consider alternative hosting options. For instance, using a server from OVH would provide similar speed but weaker DDoS protection. I've experienced attacks even with their services. The solution involves finding a more robust provider or implementing additional security measures.
You have no options! DDoS defense must start as far upstream as feasible to manage the flow and prevent congestion. After the traffic reaches your internet link, the harm is irreversible. What you can do is limit the effect of a single malicious attempt by blocking unusual patterns before they reach the server. This approach safeguards against server overload, not internet bandwidth issues.
You're right, those options don't fit what you need. The data still reaches your home through the pipe. You either have enough bandwidth to handle it or you're being overwhelmed. Consider switching to a host with stronger protection against DDOS or managing the issue yourself.
All setup on your local network won’t work because by the time it notices the traffic, it’s already too late. The DDOS flood must travel through your internet connection so you can block it. You can stop it from reaching your server, but you can’t stop it from overwhelming your internet speed. Consider moving to a genuine hosting service or using a tool like Cloudflare.
To stop someone from overwhelming the server, the most effective approach is usually geoblocking and manually blocking IP addresses that attempt excessive connections. This method works well for me—I restrict incoming traffic only to the US and UK, which helps with log spam from Russian hackers, etc. However, it doesn’t stop bandwidth usage on the wider Internet if an attack is happening. For DDoS attempts, your ISP is the one who can actually block the traffic. Trying to spot suspicious patterns automatically demands significant CPU resources on your router and has a high chance of false positives. We’d need Deep Packet Inspection, which is a complex and resource-heavy solution beyond my current interest, plus it would require a powerful device. Another option is setting up a tunnel or VPN between your server and the Internet, like Cloudflare, to filter traffic—but this would add latency to your game servers.
You can't safeguard your home network against DDoS attacks because the available bandwidth isn't sufficient for such heavy loads, and most ISPs don’t offer any protection. The safest option is to purchase an affordable DDoS-protected VPS and configure HAProxy to route traffic from your protected server to your home network. This approach hides your own IP address while also reducing the impact before the traffic reaches your local network.
