Iptables itself does not have track target so that you cannot specify a whitelist of packets that need to be processed by the Conntrack module, for example, I would like to implement: except for the source IP is the 192.168.10.0/16 network segment needs to be track, the others do not track.Of course, you can implement my requirements through the following configuration:iptables-t raw-a prerouting!-S 192.168.10.0/16-j notrack...

Welcome to the Netease cloud community to learn more about the operation experience of Netease technology products. In daily work and life, when you maintain your own servers and VPs, you may encounter such a situation: the server suddenly displays many network connections and traffic from unknown IP addresses, we need to cut off these potentially harmful Network Connections immediately.

use conntrack is that it can efficiently locate a stream and save the flow information, while the forward item can be saved in the stream ... If there is a more efficient way than locating a stream, then there is no need for conntrack, and it turns out that I have found this more efficient way.2. Too many filter entries, resulting in a sharp decline in packet performanceThe Iptables filter was completely abandoned by me, replaced by Nf-hipac and Ipset
