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.当一个女子会些武功，再拼命起来，那是比男人还难对付的。该剧讲述了丧偶多年的退休老教师齐国盛和三个性格迥异的儿子的家庭生活故事。不管如何狼狈不堪，也阻挡不了这一家人在吵吵闹闹中勇敢追爱，奋力前行。　　一个我从未透露过的秘密Soul: Diregi's Phantom PearlChapter 26
