These servers—known as middleboxes—are deployed by nation-states such as China to censor restricted content and by large organizations to block sites pushing porn, gambling, and pirated downloads. The servers fail to follow transmission control protocol specifications that require a three-way handshake—comprising an SYN packet sent by the client, an SYN+ACK response from the server, followed by a confirmation ACK packet from the client—before a connection is established.
