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.

For easier management, We can also create custom chains in a table, Place the rules set for an application in this custom chain, But custom links cannot be used directly, It can only work if it is called as an action by a default chain. We can imagine that, Custom chain is a relatively "short" chain. The rules on this "short" chain are all formulated for an application program. However, this short chain cannot be directly used, but needs to be "welded" on the default definition chain of IPTables before it can be used by IPTables. This is why the default definition "chain" needs to refer to "custom chain" as "action". This is a later remark. We will talk about it later. We can understand it more clearly in actual use.
