The attacker first forged the address to initiate a SYN request to the server (can I establish a connection?) The server will respond with an ACK + SYN (Yes + Please confirm). The real IP will think that I did not send the request and did not respond. The server does not receive a response and will retry 3-5 times and drop the connection after waiting for a SYN Time (typically 30 seconds-2 minutes).
When a client accesses a server's web service, The client sends a message to the network card, The tcp/ip stack is part of the kernel, Therefore, the client information is transferred to the web service in user space through the kernel's TCP protocol, At this time, the destination destination of the client message is on the socket (IP: Port) that the web service is listening for. When a web service needs to respond to a client request, The destination destination of the response message sent by the web service is the client, At this time, The IP and port that the web service listens on becomes the origin instead, As we said, Netfilter is the real firewall, It is part of the kernel, Therefore, if we want the firewall to achieve the goal of "fire prevention", You need to set up checkpoints in the kernel. All incoming and outgoing messages have to pass through these checkpoints. After checking, those that meet the release conditions can be released, while those that meet the blocking conditions need to be blocked. As a result, input checkpoints and output checkpoints appear. These checkpoints are not called "checkpoints" but "chains" in iptables.

Analysis: Wolf Hunters, as speed arms, rely more on attacks. However, its short life is its fatal place, so everyone often takes precedence over raising life. In fact, there is no right or wrong. I have used two numbers, one attack king made it very high and the other life king made it very high, but the result was that the attack was very high and the life king was very high. The reason was that the attack king was very high because there was no support from life and it was easy to destroy. Therefore, it is a wise choice for this arms to upgrade in a balanced way and for wolf hunters to attack kings. But, the king of a wolf hunter is extremely difficult to get, which is why more and more people give up this arm and cannot afford to play!
