Hello, I have been struggling with attacks on my CS:GO server for 5 days. Attack flies on A2S server status. You can't see his status or connect to him. I have a CS:GO server on my dedicated server with OVH GAME.
Port CS:GO: 27015
This is what I see in the server console:
IP rate limit under distributed packet load (145 buckets, 101 global count), rejecting 77.253.78.14
6398."
"IP rate limit sustained 606 distributed packets at 60.6 pps (0 buckets)."
"IP rate limit under distributed packet load (50 buckets, 101 global count), rejecting 89.65.61.181:27005.
I entered a rule into IPTables:
iptables -N Filter-DROP
iptables -N Filter-GAME
iptables -A INPUT -p udp -m udp --dport 27015 -m recent --update --seconds 30 --hitcount 5 --name vse --mask 255.255.255.255 --rsource -j DROP
iptables -A INPUT -p udp -m udp --dport 27015 -m string --hex-string "|ffffffff71|" --algo kmp --to 65535 -j Filter-GAME
iptables -A INPUT -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport 27015 -j ACCEPT
iptables -A INPUT -p udp -m udp --dport 27015 -j ACCEPT
iptables -A Filter-DROP -p udp -m udp -m recent --set --name vse --mask 255.255.255.255 --rsource -j DROP
iptables -A Filter-GAME -p udp -m udp --sport 0:27015 -j Filter-DROP
iptables -A Filter-GAME -p udp -m udp -m hashlimit --hashlimit-above 1/sec --hashlimit-burst 3 --hashlimit-mode srcip --hashlimit-name StopDoS --hashlimit-htable-expire 30000 -j Filter-DROP
iptables -A Filter-GAME -p udp -m udp -j RETURN
After entering the rules to iptables, I start to see the server, but most players have problems connecting to it.
I tried to enable it ->
https://github.com/sqproxy/sqproxy but I can't configure it, I get errors.
I would like to configure it ->
https://github.com/gnif/SteamQueryProxy but I can't, can anyone help me?
