실습에 사용되는 프로그램은 Packet tracer입니다. 또한 구성도의 기본 설정들은 생략합니다.

구성도

nat3-1-

인터페이스에 inside/outside

NAT_Router(config)#int f0/0
NAT_Router(config-if)#ip nat inside
NAT_Router(config-if)#int f1/0
NAT_Router(config-if)#ip nat outside

inside 범위 설정

NAT_Router(config)#access-list 1 permit 192.168.1.0 0.0.0.255

outside 범위 설정

NAT_Router(config)#ip nat pool dynat 1.1.1.100 1.1.1.101 netmask 255.0.0.0

acl(inside) -> pool(outside) 로 변환
