DDoS is killing me

I run my server with 0 resource (tx-admin only) and simple SYN Flood or SYNACK Flood is causing my fxserver to go down. When I get attack, my entire server is running super normal except the Fxserver.
Tons of server thread hitch warning > Crash > Tx-admin restart > Fxserver dead > Cannot restart itself

  1. Linux Centos 6
  2. 1686 Artifacts
  3. OVH Host
  4. All firewall rules / Iptables setup properly.

99% packets blocked by OVH and only very small packets can reach in the server, and those small packets just cause my fxserver to shut down.
a) Do I need to modify any Artifacts file to protect my server ?
b) Any other anti DDoS solution for Fivem specifically?

  • I have been looking for a post about ddos problem and not even one post talked about this.

That’s because you need to stop these attacks at the firewall. No change in FiveM will stop an attack on a service running on a certain port.

I suggest you consult Google and network forums for ways to properly use iptables to block attacks. Capture packets with tcpdump while the server is not running to see where they are coming from and then simply drop them.
