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.After the INPUT chain is emptied, there are no rules for the INPUT chain in the filter table, but it can be seen that the default policy of the INPUT chain is ACCEPT, that is, the INPUT chain "releases" all messages sent to the local machine by default, accepts all messages when there are no rules, and releases messages by default when the messages are not matched by any rules.A special animated adaptation of Sir Michael Morpurgo’s children’s book Mimi And The Mountain Dragon.Mimi And The Mountain Dragon is the story about a village that quakes in feature of the mighty Mountain Dragon.
