When a client accesses a server's web service, The client sends a message to the network card, The tcp/ip stack is part of the kernel, Therefore, the client information is transferred to the web service in user space through the kernel's TCP protocol, At this time, the destination destination of the client message is on the socket (IP: Port) that the web service is listening for. When a web service needs to respond to a client request, The destination destination of the response message sent by the web service is the client, At this time, The IP and port that the web service listens on becomes the origin instead, As we said, Netfilter is the real firewall, It is part of the kernel, Therefore, if we want the firewall to achieve the goal of "fire prevention", You need to set up checkpoints in the kernel. All incoming and outgoing messages have to pass through these checkpoints. After checking, those that meet the release conditions can be released, while those that meet the blocking conditions need to be blocked. As a result, input checkpoints and output checkpoints appear. These checkpoints are not called "checkpoints" but "chains" in iptables.

《笑傲江湖》热播后，网络上关于这部剧的讨论就一直没有停过，现在电视剧结束了，越来越多的网友开始发表自己的看法和感受
唐贞观年间，西凉叛乱，李世民御驾亲征，被敌帅苏宝同围困在锁阳城，主帅薛仁贵也被苏宝同的毒刀所害，命在旦夕。薛仁贵之子薛丁山获知父亲遇难，参加了二路平乱大军，西去救父。一路上，薛丁山收服山贼窦一虎、大战苏宝同，最终将薛仁贵和李世民从锁阳城救出。李世民班师回朝，留下薛氏父子继续平乱。苏宝同搬来救兵并派出手下大将樊洪前去挑战。樊洪之女樊梨花对薛丁山一见钟情，不惜和家人反目，献关投薛。薛丁山却听信谄言，误以为樊梨花是杀父害兄的不义之人，将樊梨花赶出唐营。后来在程咬金等人的撮合帮助下，上演了“三休三请樊梨花”的动人故事。最终几经离合，薛丁山和樊梨花终于结为夫妻。在他们的共同努力下，唐军平定了西凉之乱。
《游侠张三丰》是张国荣早期古装电视作品，张三丰一角由万梓良出演，张国荣演的是懿文太子，全剧以太子和富豪之女的恋情以及宫廷权利的斗争为线索，其中穿插了许多人物的悲欢故事，张三丰则是一个游走于宫廷和江湖中的侠仕，一面阻挡着江湖的恶势力破坏江山，一面与朱元璋的冷酷和猜疑做斗争，同时又在帮助这对痴男怨女，然而历史注定了懿文太子的悲剧的命运。张国荣的演技仍然带着一份青涩，但比起《浣花》则成熟多了，写到这里不禁想起万梓良在看哥哥表演MONICA的时候跟着蹬脚拍手的样子，想来他们的友谊是在《浮生六劫》《大内群英续》等一系列合作中建立起来的吧。
