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.　　在涡流岛上，神圣联军的先头部队遭到幽弥狂及其战友的强力扑杀。随后蛮小满、雪伦（敖磊 配音）、蛮吉随着镜心登岛，惨烈的战斗撼动元泱界的每一个角落……这部连续剧，特别是试点剧集，取得了相当大的成功。第一季获得了艾美奖编舞奖，还获得了金球奖和格莱美奖的提名。*书*吧(）俗话说，天做孽犹可活，自作孽不可活。
