ip nat:表示设置应用NAT的内网和外网的接口。inside:表示该接口连接内部网络。source list 1:表明内网地址列表。interface serial0/0:传输所经由的外网接口(地址),overload表明启用端口复用。
①ip nat inside source list n pool POOL_NAME 当list n为标准访问列表---access-list 1 permit a.b.c.d ,数据包的源地址 满足list n(a.b.c.d),源地址转换为POOL_NAME地址 当list n为扩展访问列表--- access-list 100 permit tcp A B ,数据包的协议、 源地址、目的地址、端口号等都要匹配list ...
结论就是,ip nat source不用在接口上指inside或者outside,要打开ip nat enable,然后转发过程不一样,路由进虚接口---NAT转换---真正路由转发,然后两边是对称的。
加了overload的话,才能实现多个内网ip转换成一个公网ip,从而实现多个内网ip都能访问internet的目的,如果不加的,地址转换只能实现一对一的转换,即,同一时刻,只能有一台机器的ip被转换成公网IP,也就是说,同一时间只有一台内网机器访问internet,解答完毕!
# ip nat inside source list 1 int G0/0 overload #将ACL表复用到G0/0 # ip route 0.0.0.0 0.0.0.0 G0/0 #默认路由 # interface G0/0 #配置NAT外网 # ip nat outside # interface G0/1 #配置NAT内网 # ip nat inside 1. 2. 3.
使用ip nat outside source list命令(动态 NAT)而不是ip nat outside source static命令(静态 NAT)的主要区别在于,在(为 NAT 配置的)路由器检验数据包的转换标准之前,在转换表中没有条目。在上述示例中,SA 为 172.16.88.1 的数据包(进入路由器 2514x 的外部接口)符合访问列表 1,即ip nat outside source ...
ip nat inside source static 1.1.1.1 2.2.2.2 ip nat inside destination list 1 pool roc ip nat outside source static 2.2.2.2 1.1.1.1 ip nat outside destination list 2 pool aking 解析以上几条命令: 把从inside接口进入,从outside接口出去的数据包源地址1.1.1.1转换为2.2.2.2 ...
