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.冬冬是幼儿园大班的孩子。妈妈晓燕下岗后不久，爸爸大宇也在人员精简中，把最后的机会让给了刚刚失去丈夫的同事小孙。本来，爸爸一个人上班时，日子就过得非常紧张。为了最大限度的节省开支，冬冬的中午饭被改在家里吃，冬冬想要的一只花背小乌龟……1829年，尼古拉·果戈裡，年輕的第三局記錄員，他自己的詩集淺薄平庸，靠買賣焚燒自己的詩集製造銷量。果戈裡和探員尼雅科夫調查一起疑團重重的年輕女性系列兇殺案，因為當地人傳言，兇手是名為黑暗騎士的魔鬼，必須借助來自黑暗的力量來對抗黑暗，因為在這個世界裡沒有光明……其实在她们心里，还是自己的娃最好。跳过依旧在燃烧的残木火堆，迅速朝对面冲去。新的学年，少女之间的大战争逐渐推向高潮……他四下乱看，又对窗外看，院子里一个人也没有。
