The first packet discarding scheme will have a slight impact on the user experience, because discarding the first packet retransmission will increase the response time of the service. In view of this, a better TCP Proxy scheme has been developed. All SYN data messages are accepted by the cleaning equipment and processed according to the SYN Cookie scheme. The IP address that successfully established the TCP three-way handshake with the device is determined to be a legitimate user to join the white list. The device disguises the real client IP address, completes the three-way handshake with the real server, and then forwards the data. However, if there is no IP address that shakes hands with the device three times within the specified time, it is determined that the malicious IP address is blocked for a certain period of time. In addition to SYN Cookie combined with TCP Proxy, the cleaning equipment also has the ability to detect a variety of abnormal TCP flag bit packets, and identifies normal access and malicious behavior by returning unexpected responses to SYN messages to test client responses.　　上世纪30年代的上海，叱咤风云的帮派大佬，不甘寂寞的交际花，说着地道上海话的日本妹夫，只收交通费的杀手，被冷落却忠诚的姨太太，外表光鲜的电影皇后，深宅大院里深不可测的管家，偶尔偷腥的电影皇帝，荷尔蒙满溢大脑的帮派小弟，一心想要破处的处男，善良的妓女，随波逐流的明星丈夫，投靠日本人的帮派二哥，日理万机却抽空恋爱的戴先生。Russia: 3,100,0005.
