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.刘邦的家人再次被押了回去，吕雉就知道会是这样的结果，所以自从来到城下的那一刻，她一直注意着丈夫的态度。The above design error stems from confusing the hierarchical structure of "role" with that of "person" and mistaking "Has-A" for "Is-A".
