Cisco Secure PIX Firewall Software 릴리스 6.0 이상에서는 Cisco VPN Client 3.x 및 4.x의 연결을 지원합니다. 이 샘플 컨피그레이션에서는 PIX를 터널 엔드포인트로 연결하고 트래픽을 암호화하는 두 가지 VPN 클라이언트 버전을 보여줍니다. 이 컨피그레이션에서는 주소 풀이 IPSec(IP Security)에 할당되도록 구성됩니다.
이 샘플 컨피그레이션에서는 PIX가 적절한 통계, 관로 또는 액세스 목록과 함께 이미 작동한다고 가정합니다. 이 문서는 이러한 기본 개념을 설명하기 위한 것이 아니라 Cisco VPN Client에서 PIX에 대한 연결을 보여주기 위한 것입니다.
이 문서의 정보는 다음 소프트웨어 및 하드웨어 버전을 기반으로 합니다.
PIX Software 릴리스 6.2(1)
참고: 이 설정은 PIX Software Release 6.2(1)에서 테스트되었지만, 이전 릴리스에서 6.0(1) 이후 릴리스와 함께 작동해야 합니다.
Cisco VPN Client 버전 3.6 Rel
참고: 이 설정은 VPN Client v4.0 Rel에서 테스트되었지만 이전 릴리스에서 3.0까지 최신 릴리스로 복구해야 합니다.
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.
문서 규칙에 대한 자세한 내용은 Cisco 기술 팁 표기 규칙을 참고하십시오.
이 섹션에는 이 문서에서 설명하는 기능을 구성하기 위한 정보가 표시됩니다.
이 문서에서는 다음 네트워크 설정을 사용합니다.
참고: 명령 조회 도구(등록된 고객만 해당)를 사용하여 이 문서에 사용된 명령에 대한 자세한 내용을 확인하십시오.

VPN 클라이언트를 사용하여 새 연결을 생성하려면 다음 단계를 완료합니다.
VPN Client를 시작한 다음 New(새로 만들기)를 클릭하여 새 연결을 생성합니다.
새 연결에 대한 구성 정보를 입력합니다.
Connection Entry(연결 항목) 필드에서 항목에 이름을 지정합니다.
Host 필드에 PIX의 공용 인터페이스의 IP 주소를 입력합니다.
Authentication(인증) 탭을 선택한 다음 그룹 및 비밀번호(확인을 위해 두 번)를 입력합니다.
마쳤으면 저장을 클릭합니다.
Connect(연결)를 클릭하여 PIX에 연결합니다.
이 섹션을 사용하여 컨피그레이션이 제대로 작동하는지 확인합니다.
Output Interpreter 도구(등록된 고객만 해당)(OIT)는 특정 show 명령을 지원합니다. OIT를 사용하여 show 명령 출력의 분석을 봅니다.
show crypto isakmp sa - 피어에서 현재 IKE(Internet Key Exchange) 보안 연결(SA)을 모두 봅니다.
show crypto ipsec sa - 현재 SA에서 사용하는 설정을 봅니다.
이 섹션에서는 컨피그레이션 문제를 해결할 수 있습니다.
참고: debug 명령을 사용하기 전에 디버그 명령에 대한 중요 정보를 참조하십시오.
debug crypto ipsec - 2단계의 IPSec 협상을 확인하는 데 사용합니다.
debug crypto isakmp - 1단계의 ISAKMP 협상을 확인하는 데 사용합니다.
debug crypto engine - 암호화된 트래픽을 표시합니다.
다음은 Cisco VPN 3.0.x Client에서 생성된 올바른 디버그 샘플입니다.
