What kind of ddos did you got? If it is a syn flood, just limit the syn ack answers with your firewall. A game server normally don’t need much TCP traffic, so you can limit it to 10/sec.

It's obviously a ddos attacks, so at first I tried different protections (iptables rules, apf, csf firewalls, ddos deflate and none of them helped). I also asked my ISP to stop all the international traffic, but that didn't help either because the IPs are spoofed. Is there any protection from these kinds of attacks and if yes, what is it? -------------------------------------------------------------------------------- _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: https://list.valvesoftware.com/cgi-bin/mailman/listinfo/hlds
