These iptables rules can cause any performance problem for a webserver?
Code: Select all
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p tcp -m tcp --tcp-flags FIN,SYN,RST,ACK SYN -j SYN_FLOOD
-A SYN_FLOOD -m limit --limit 5/sec --limit-burst 10 -j RETURN
-A SYN_FLOOD -j DROP
Thanks.
