一、实验环境
eNSP V100R003C00SPC100版本
二、实验拓扑
三、实验需求
1,PC1通过NAT静态转换为8.8.8.8地址访问外网114.114.114.114
2,PC2和PC4通过NAT动态转换为212.0.0.0网段的地址访问外网地址114.114.114.114
3,PC3通过NAT端口多路复用访问外网地址114.114.114.114
4,外网13.0.0.2能够通过R1的端口映射访问企业网内部的httpd网页
四、实验步骤
配置PC1,PC2,PC3,PC4,Server
PC1配置
PC2配置
PC3配置
PC4配置
Server配置
1，设置地址
2，配置Httpd服务
