一、實驗環境

eNSP V100R003C00SPC100版本

二、實驗拓撲

三、實驗需求

1,PC1通過NAT靜態轉換爲8.8.8.8地址訪問外網114.114.114.114

2,PC2和PC4通過NAT動態轉換爲212.0.0.0網段的地址訪問外網地址114.114.114.114

3,PC3通過NAT端口多路複用訪問外網地址114.114.114.114

4,外網13.0.0.2能夠通過R1的端口映射訪問企業網內部的httpd網頁

四、實驗步驟

配置PC1,PC2,PC3,PC4,Server

PC1配置

PC2配置

PC3配置

PC4配置

Server配置

1，設置地址

2，配置Httpd服務

新建一個html後綴的文本，在服務器信息中選擇HttpServer的80端口，文件根目錄中加入html後綴的文本。
