안녕하세요.
오늘은 [2025][Juniper SRX #27] Static NAT - One to One NAT 설정해보겠습니다.
User01 - 10.1.1.1 Ge-0/0/0 192.168.10.83를 통해서 SNAT하고
User02 - 10.1.1.2 Ge-0/0/0 192.168.10.83를 통해서 SNAT하고
HTTP SERVER - 20.1.1.1에 static nat를 설정 하겠습니다.
외부에서 DMZ Server에 통신할때 192.168.10.84 -> 20.1.1.1 변경됩니다.
HTTP Server 20.1.1.1 외부로 통신할때 192.168.10.84로 변경 됩니다.
1.SRX01 기본설정 입니다.
1-1 SRX 디폴트로 설정되어진 설정값을 삭제 합니다.

One to One NAT ( Static NAT)를 사용 해서 192.168.10.84 <---> 20.1.1.1로 설정합니다.
서버는 외부 통신할때 Source IP 20.1.1.1 -> 192.168.10.84 변경됩니다.
외부에서 DMZ서버랑 통신 할때 Destination IP 192.168.10.84 -> 20.1.1.1 변경 됩니다.
우선 외부 untrust에서 dmz로 통신하기 위해서 방화벽 정책을 설정 합니다.

그 이유는 SRX에서 Proxy로 IP POOL에 사용하는 IP 주소를 설정 해야지 Ge-0/0/0가 ARP에 대해서 응답합니다.
