NAT的三种方式：

一、端口NAT

acces-list 1 permit IP/Mask

ip nat inside source list “number” interface fastethernet overload

 

二、静态NAT

ip nat inside sourece static IP

 

三、动态NAT—以地址池的方式来对于NAT映射

access-list “number” permit IP/Maks

ip nat pool cisco IP~IP netmask Maks

ip nat inside sourece list "number" pool cisco overload
