How to protect against DDOS ?
Mitigating DDoS attacks isn't possible using consumer routers.
Mitigating DDoS attacks is extremely challenging. The best approach is to reroute traffic away from your limited bandwidth connection toward a distant server with ample capacity, allowing you to absorb the assault effectively. This explains why services like Cloudflare are popular for such protection. For gaming traffic, there isn’t a standard solution. That’s why platforms like Xbox and PSN have been temporarily disabled during major attacks, as manual blocking becomes a continuous cat-and-mouse effort.
It’s not quite correct to claim you can’t reduce the impact of DDoS attacks, especially given recent progress. Several methods exist for reducing their effect, including deploying a scrubbing network, applying edge-level protection, and adopting newer stateful strategies. Stateful mitigation inspects each connection based on its history, helping you understand whether traffic is genuine or harmful. Keeping a stateful log table enables smarter decisions about allowing or denying packets.

However, the only options you really have are minimizing the impact by not engaging with the traffic and hoping it doesn’t reach your connection. A DDoS attack overwhelming your bandwidth is a problem you can’t stop without additional equipment inside your ISP network to handle the load. While you might find a public IP address that can help filter or redirect the traffic, it introduces delays and probably costs money, making it less practical for running a local game server.
Delays vary by service and pathways. My connection adds just 4ms to Amsterdam’s GlobalSecureLayer site. At such a small amount, performance changes will be imperceptible.
Yes, that makes sense. However, this adds delay and increases VPN expenses. I believe it’s justified—either by running the server on a VPS instead of routing traffic back to your own network, thus avoiding latency issues. At the same time, filtering at the home server isn’t feasible. The only viable option is to block the traffic before it reaches your internet connection, no matter how you set it up.
See above message. and yes, you can’t do any mitigation on your home network since no home ISP wants to deal with attacks at their upstream
