When the SYN gateway receives the SYN packet from the client, it directly forwards it to the server. After receiving the SYN/ACK packet from the server, the SYN gateway forwards the packet to the client and sends the ACK confirmation packet to the server in the name of the client. At this time, the server enters the connected state from the semi-connected state. When the client confirms the arrival of the packet, it forwards if there is data, otherwise it discards it. In fact, the server has a connection queue in addition to maintaining the semi-connection queue. If SYN attack occurs, the number of connection queues will increase, but the number of connections that the general server can withstand is much larger than the number of semi-connections, so this method can effectively reduce the attack on the server.
After executing the command to add rules, look at the INPUT chain again and find that the rules have been successfully "appended" to the end of the INPUT chain. Now, the first rule indicates to discard all messages from 192.168. 1.146 and the second rule indicates to accept all messages from 192.168. 1.146. What is the result? Practice shows true knowledge. I used the ping command to send a message to the 156 host again on the 146 host, and found that the ping still failed. It seems that the second rule did not take effect.
