The firewall sets the SYN forwarding timeout parameter (the firewall for state detection can be set in the state table), which is much less than the timeout time of the server. When the client sends the SYN packet and the server sends the acknowledgement packet (SYN + ACK), if the firewall has not received the acknowledgement packet (ACK) from the client by the time the counter expires, it sends the RST packet to the server to cause the server to delete the half connection from the queue. It is worth noting that the setting of gateway timeout parameters should not be too small or too large. If the setting of timeout parameters is too small, it will affect normal communication. If the setting is too large, it will also affect the effect of preventing SYN attacks. This parameter must be set according to the network application environment.

In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).
