Hello, I have a Ubuntu VPS server with OpenVPN (I sell openvpn accounts) installed that works pretty good but some days ago the server started to shut down everyday. I asked to the administrator and he said it was because DDoS attack and my server was blackholed to protect the network. The thing I can note in VPS graphs is a violent increase of network use (TX Read 1gbps) before it goes down. I tried with : ufw only OpenVPN port opened many iptables configurations ipset to blacklist all non-chilean IPs (I'm from Chile) fail2ban default configuration So maybe attack is from the inside, a connected user to the vpn can attack the network from the inside?. The solution can not decrease the speed/latency performance because is VPN FOR GAMING My budget is not high but I hope you can help me, need guaranteed results. Regards

hi! those ddos attacks can be from the inside or from the outside. try to read the logs of the OpenVPN or at least look at the ifconfig command's output - which network interface consumes a lot of traffic.

I'm professional developer and designer. I have overlooked your project details and understand the requirement. Allow me to work on your project. Wating for your reply. ** Should I fresh/re-install Ubuntu on your VPS hosting. In this way your problem will be solved. ** Is there any customer data you need to save? Have you take backup of all data? ** Country Ip can be blacklist on server panel. ** This is mind work project. I've bid lowest as possible. I know this will consume time.

What I would suggest is capture the traffic and Identify its origin. Next we can look at the best way to protect against such attacks, with your current setup there is not much you can do. I am not sure what your budget is or how many servers you currently are running, but there are several ways that we can attack this.
