Can somebody post some iptable rules to defend against these basic attacks such as SSH brute force, syn., etc. Also if somebody can recommend decent free/cheap firewalls On May 18, 2012 12:27 PM, "Ivan Ivanov" <harryp...@abv.bg> wrote: > > > Ops.

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. > > > > From: Ivan Ivanov > Sent: Friday, May 18, 2012 4:49 PM > To: hlds@list.valvesoftware.com > Subject: [hlds] HLDS ddos attacks [spoofed IPs] > > Hello, > > For the last few days I've been attacked by a big(huge) number of international IPs [Russia, USA, Korea, China, Italy etc..]. 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.
