Amazon EC2 인스턴스의 Linux 인스턴스와 Cisco 집중기를 통해 원격 네트워크간에 strongSwan을 사용하여 VPN을 설정하고 있습니다. Linux 인스턴스 자체의 패킷을 원격 서브넷의 시스템으로 라우팅해야합니다.

연결은 정상이지만 패킷이 라우팅되지 않습니다.

특정 라우팅 규칙을 설정해야한다고 생각합니다. 어떻게해야합니까?

소프트웨어

• 리눅스 커널 3.5.0-41,
• 우분투 12.10,
• strongSwan 5.1.1 (소스에서 빌드),
• iptables-규칙이 없습니다.

회로망

현지

• Amazon Elastic IP : 56.xxx
• 공개 LAN IP : 172.xxx
• 로컬 가상 서브넷 : 10.254.0.0/16
• 로컬 가상 IP : 10.254.5.174

먼

• Cisco 집중 장치의 공용 IP : 62.xxx
• 원격 서브넷 : 10.192.0.0/12
