实验7——网络地址转换技术(NAT)

静态地址转换

interface s0/0/0 \\接入运营商接口
ip nat outside  \\ 设置外部接口
interface s0/0/1 \\内网接口
ip nat inside  \\设置内部接口
ip nat inside source static [内部本地IP] [内部全局IP]
show ip nat translation  \\查看结果
           

动态地址转换

interface s0/0/0 \\接入运营商接口
ip nat outside  \\ 设置外部接口
interface s0/0/1 \\内网接口
ip nat inside  \\设置内部接口
ip nat pool [名称] [动态地址起始值] [动态地址结束值] netmask [子网掩码]
access-list [名称] permit [子网络号] [子网掩码反码] 
ip nat inside source list [名称] pool [名称]
           

端口多路复用地址转换

interface s0/0/0 \\接入运营商接口
ip nat outside  \\ 设置外部接口
interface s0/0/1 \\内网接口
ip nat inside  \\设置内部接口
ip nat pool [名称] [动态地址起始值] [动态地址结束值] netmask [子网掩码]
access-list [名称] permit [子网络号1] [子网掩码反码] 
access-list [名称] permit [子网络号2] [子网掩码反码]
access-list [名称] permit [子网络号3] [子网掩码反码]
ip nat inside source list [名称] pool [名称]
