This solution requires that you only accept NEW connections that have SYN set. Something like -m conntrack --ctstate ESTABLISHED -j ACCEPT -p tcp --syn -m conntrack --ctstatus NEW -j ACCEPT -p udp -m conntrack --ctstatus NEW -j ACCEPT -p tcp -j REJECT --reject-with tcp-reset -j REJECT yes, that is indeed a good idea to do a tcpkill on connections using conntrack :-) -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
