1误解一：inside和outside 大家常规的理解可能认为inside就是指私网；outside就是公网。正解一 inside和outside是在接口上用户自己定义的，只不过我们习惯于在路由器的内部接口定义inside；外部接口定义outside。2误解二:source和destination 大家在配置IP NAT的时候可能会用如下命令：ip nat inside source static/route...
*重点一:ip nat outside dynamic模式,只有发生转换,translation表内才有数据。即必须先outside---访问-->inside,inside才能访问outside。 相反,在ip nat inside dynamic模式,必须先inside---访问--->outside,产生转换表后,outside的包才能发回inside侧。 三、IP nat outside 例子 OldserverIP:10.1.1.8 因为性...

3. 在R1中的S0/0和F1/0 分别配置NAT的outside和inside 那么我们来看一下具体的配置: ① 配置ACL -- 这里只允许192.168.10.0/24的网段IP地址可以转换成公网IP ip access-list standard permitinternet permit 192.168.10.0 0.0.0.255 ② 开启在R1 的S0/0端口的NAT的PAT设置 ...
inside|outside local和inside|outside global的一对一映射 D-Lab(config)#ip nat {inside|outside} source static <inside local> < inside global> 这样就在NAT表中创建了一个永久表项。 配置示例: D-Lab#config t D-Lab(config)#int e0 D-Lab(config-if)#ip nat inside ...

② ip nat outside source 与 ip nat inside destination 等价 功能1:将从外到内的IP包的源地址进行转换(外部全局—>外部局部) 功能2:将从内到外的IP包的目的地址进行转换(外部局部—>外部全局) ③ ip nat inside destination 功能1:将从内到外的IP包的目的地址进行转换(外部局部—>外部全局) ...
