이 번역에 관하여

Cisco는 전 세계 사용자에게 다양한 언어로 지원 콘텐츠를 제공하기 위해 기계 번역 기술과 수작업 번역을 병행하여 이 문서를 번역했습니다. 아무리 품질이 높은 기계 번역이라도 전문 번역가의 번역 결과물만큼 정확하지는 않습니다. Cisco Systems, Inc.는 이 같은 번역에 대해 어떠한 책임도 지지 않으며 항상 원본 영문 문서(링크 제공됨)를 참조할 것을 권장합니다.

소개

이 문서에서는 라우터가 PIX의 동적 IPsec 연결을 수락하도록 설정하는 방법을 보여 주는 샘플 컨피그레이션을 제공합니다.사설 네트워크 10.2.1.x가 인터넷에 액세스하는 경우 원격 라우터는 NAT(Network Address Translation)를 수행합니다.PIX Security Appliance 뒤에 있는 10.2.1.x에서 프라이빗 네트워크 10.1.1.x로의 트래픽은 NAT 프로세스에서 제외됩니다.IPsec 터널은 트래픽(10.1.1.x)이 원격 네트워크(10.2.1.x)가 있는 라우터와 PIX Security Appliance의 연결을 시작하는 경우에만 설정됩니다. PIX는 라우터에 대한 연결을 시작할 수 있지만 라우터는 PIX에 대한 연결을 시작할 수 없습니다.

이 컨피그레이션에서는 Cisco IOS® 라우터를 사용하여 공용 인터페이스(외부 인터페이스)에서 동적 IP 주소를 수신하는 보안 어플라이언스와 함께 동적 IPsec LAN-to-LAN(L2L) 터널을 생성합니다. DHCP(Dynamic Host Configuration Protocol)는 서비스 제공자로부터 동적으로 IP 주소를 할당할 수 있는 메커니즘을 제공합니다.이렇게 하면 호스트가 더 이상 필요하지 않을 때 IP 주소를 재사용할 수 있습니다.

PIX 6.x가 라우터에서 동적 IPsec 연결을 수락하는 시나리오에 대한 자세한 내용은 NAT를 사용하여 PIX-to-Router Dynamic-to-Static IPSec 구성을 참조하십시오.

라우터가 6.x를 실행하는 PIX 방화벽에서 동적 IPsec 연결을 수락하는 시나리오에 대한 자세한 내용은 NAT 컨피그레이션이 포함된 Router-to-PIX Dynamic-to-Static IPsec 예를 참조하십시오.

PIX/ASA Security Appliance가 Cisco IOS 라우터에서 동적 IPsec 연결을 허용하도록 하려면 고정 IOS 라우터와 NAT가 있는 동적 PIX/ASA 7.x 간 IPsec를 참조하십시오.

PIX/ASA Security Appliance 7.x가 다른 PIX 6.x에서 동적 IPsec 연결을 수락하는 시나리오에 대한 자세한 내용은 PIX/ASA 7.x PIX-to-PIX Dynamic-to-Static IPsec with NAT 및 VPN Client Configuration 예를 참조하십시오.

사전 요구 사항

요구 사항

이 컨피그레이션을 시도하기 전에 PIX와 라우터가 모두 IPsec 터널을 설정하기 위한 인터넷 연결을 가지고 있는지 확인합니다.

이 문서에서는 퍼블릭 및 프라이빗 인터페이스에서 IP 주소를 이미 할당했으며 원격 VPN 디바이스의 IP 주소를 ping할 수 있다고 가정합니다.

사용되는 구성 요소

이 문서의 정보는 다음 소프트웨어 및 하드웨어 버전을 기반으로 합니다.

  • Cisco IOS Software 릴리스 12.4를 실행하는 Cisco 3600

  • PIX 515E Series Security Appliance Software 릴리스 7.x 이상

이 문서의 정보는 특정 랩 환경의 디바이스를 토대로 작성되었습니다.이 문서에 사용된 모든 디바이스는 초기화된(기본) 컨피그레이션으로 시작되었습니다.현재 네트워크가 작동 중인 경우, 모든 명령어의 잠재적인 영향을 미리 숙지하시기 바랍니다.

관련 제품

Cisco ASA 5500 Series 버전 7.x는 PIX 버전 7.x와 유사한 소프트웨어 버전을 실행합니다.이 문서의 구성은 두 제품 라인에 모두 적용됩니다.

표기 규칙

문서 규칙에 대한 자세한 내용은 Cisco 기술 팁 규칙을 참조하십시오.

배경 정보

PIX에서 access-list 및 nat 0 명령이 함께 작동합니다.10.1.1.0 네트워크의 사용자가 10.2.1.0 네트워크로 이동하면 액세스 목록을 사용하여 10.1.1.0 네트워크 트래픽을 NAT 없이 암호화할 수 있습니다.라우터에서 access-list 명령은 10.2.1.0 네트워크 트래픽을 NAT 없이 암호화하는 데 사용됩니다.그러나 동일한 사용자가 다른 곳(예: 인터넷)으로 이동하면 PAT(Port Address Translation)를 통해 외부 인터페이스 IP 주소로 변환됩니다.

이는 PAT를 통해 터널에서 트래픽이 PAT를 통과하지 못하도록 PAT Security Appliance에서 필요한 컨피그레이션 명령과 PAT를 통해 실행되도록 인터넷에 대한 트래픽입니다. 

access-list nonat permit ip 10.1.1.0 255.255.255.0 10.2.2.0 255.255.255.0
