The Iptables firewall not only provides function to filter data, but also provides a function to transfer package as well as NAT. It is used to design secure work by personal and pany. But for various reasons, the Iptables is configured by inputting mands, which means that users must be familiar to the mands. So, the paper designs and implements Iptables interfacial management tool which bases on website. The user can configure it simpler and more convenient by friendly graphics interfacial. This system uses Browser/Server mode to configure Iptables by modifying iptbales configuration files on web. The system is constituted by the following modules: the rule of addition, the rule of deleting, and the rule of insertion, the rule of replacing, the mechanism of stating, shutdown firewall, start firewall, and restarting firewall. The users can configure Iptables firewall just by login the web and clicking mouse. Key words: Iptables Firewall。 Browser/Server。 package filter 目 錄 論文總頁(yè)數(shù): 22 頁(yè) 1 引 言 .......................................................................................................................... 1 2 防火墻基本理論 ............................................................................................................ 1 防火墻技術(shù)分類(lèi) ...................................................................................................... 2 包過(guò)濾技術(shù) ........................................................................................................ 2 代理技術(shù) ............................................................................................................ 2 狀態(tài) 監(jiān)視技術(shù) ..................................................................................................... 2 2. 2 包過(guò)濾防火墻工作原理 .......................................................................................... 2 Iptables 防火墻簡(jiǎn)介 .................................................................................................. 3 Netfilter 組件 ...................................................................................................... 3 Iptables 組件 ....................................................................................................... 3 Iptables 工作原理 ................................................................................................... 3 Iptables 規(guī)則表簡(jiǎn)介 ............................................................................................ 3 Iptables 的工作流程 ............................................................................................ 4 ....................................................................................................................... 4 系統(tǒng)摘要 ................................................................................................................ 4 系統(tǒng)設(shè)計(jì)模式 ......................................................................................................... 4 4 開(kāi)發(fā)環(huán)境及工具 ............................................................................................................ 5 開(kāi)發(fā)環(huán)境 ................................................................................................................ 5 開(kāi)發(fā)工具 ................................................................................................................... 6 5 系統(tǒng)構(gòu)成 ...................................................................................................................... 6 系統(tǒng)基本構(gòu)成 .......................................................................................................... 6 功能模塊構(gòu)成 .......................................................................................................... 7 添加規(guī)則功能模塊 .............................................................................................. 7 刪除規(guī)則功能模塊 ............................................................................................. 7 插入規(guī)則功能模塊 .............................................................................................. 7 替換規(guī)則功能模塊 ....................................................................
