We know that IPTables acts according to rules. Let's talk about rules. Rules are actually predefined conditions for network administrators. Rules are generally defined as "if the packet header meets such conditions, this packet will be processed in this way". The rules are stored in the packet filtering table in kernel space, specifying the source address, destination address, transport protocol (such as TCP, UDP, ICMP), service type (such as HTTP, FTP, and SMTP), and so on. When packets match the rule, iptables processes these packets according to the methods defined by the rule, such as accept, reject and drop. The main task of configuring a firewall is to add, modify, and delete these rules.

"This time we can get that position out of danger, All by one radio station, At that time, we used rifle butts, stones, bayonets and even belts and helmets to fight these rats hand to hand. But I can't, There are too many of them, And you can take care of the earth and not the sky, Either killed by a big mouse or stung by a big wasp, Even some soldiers were anxious and hugged with big rats. And bite it with his teeth, However, this will not change the overall situation at position 149, which is very unfavorable to us. So it didn't last long, Seeing that the position was about to fall, The impression is that a person in our company, Should be a company correspondent, He sent the message directly to the back on the radio. Request the artillery to cover position 149, To live or die with the position in the way of "firing at me", Because I was very close to him, So I could hear what he was shouting, I thought I wanted to die bravely, But in the end, Through the superior order he conveyed, The response we got was to evacuate us to a hillside due north of position 149 in 3 minutes.

All of them were bent on killing one more one to avenge their comrades. I remember very clearly that I saw with my own eyes that at least three comrades had been bitten off their arms and necks by that big mouse. One of them had his stomach bitten through and his intestines flowed all over the floor, but they were still fighting.
