In fact, the scene we described above is not perfect, Because the target address of the message accessed by the client may not be the local machine, but other servers. When the kernel of the local machine supports IP_FORWARD, we can forward the message to other servers. Therefore, at this time, we will mention other "levels" in iptables, that is, other "chains". They are "before routing", "forwarding" and "after routing". Their English names are

By default, the changes we make to the "firewall" are "temporary". In other words, when the iptables service is restarted or the server is restarted, the rules we normally add or the changes we make to the rules will disappear. In order to prevent this from happening, we need to "save" the rules.

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).
Unconnected queue: In the three-way handshake protocol, the server maintains an unconnected queue that opens an entry for each client's SYN packet (syn=j), which indicates that the server has received the SYN packet, sends a confirmation to the client, and is waiting for the client's confirmation packet. The connection identified by these entries is in Syn_RECV state on the server. When the server receives the confirmation package from the customer, the entry is deleted and the server enters ESTABLISHED state.
