When the client SYN packet arrives at the filter gateway, the SYN agent does not forward the SYN packet, but actively replies the SYN/ACK packet to the client in the name of the server. If the client's ACK packet is received, it indicates that this is normal access. At this time, the firewall sends the ACK packet to the server and completes three handshakes. The SYN agent actually replaces the server to deal with SYN attacks. At this time, the filter gateway itself is required to have strong ability to prevent SYN attacks.

When she came to Qingdao, she had to mention Kang Yue, the pride of Qingdao women's lifting in recent years. She was not only the champion of the National Games and the national champion, but also the world champion in the World Championship. In her heyday, Kang Yue's result in the 75kg category was 30kg higher than that of the domestic runner-up, almost the king of 75kg. Speaking of the day when I first arrived at the sports school, Liu Eryong still remembers vividly, "I saw her for the first time when I was selecting materials. The little girl was dirty in this school uniform. Her family lived in a small temporary house built by the sea. Her parents made a living by fishing for sea vegetables and her family was very poor. However, she has a very good talent and worked very hard after choosing a sports school. She almost never missed classes or asked for leave. Sometimes when she was injured, she was not allowed to practice and let her rest. The child cried and begged us whether my arm was injured and I could practice my legs and waist. Don't let me rest. With talent and hard work, Kang Yue was chosen by the province after less than two years of practice in our country. In the third year, she won the championship of the City Games and began to rule the women's 69 and 75 kg categories. She ruled for 10 years. The result of Shenyang National Games was 30 kg higher than that of the second place and 50 kg higher than that of the 2012 Olympic champion. This gap is amazing! "
