저는 SSH를 사용하고 있으며 한동안 그렇게 해왔습니다. 새로운 곳으로 이사하고 새 라우터를 구입했습니다. 이제 로컬 IP를 통해서만 ssh를 사용할 수 있습니다. 이전에 SSH를 통한 외부 액세스를 위해 포트 전달을 설정한 경우 로컬 IP가 더 이상 작동하지 않습니다.
예를 들어, 한 머신의 경우 다음 명령(Raspberry Pi에 연결됨)이 제대로 작동합니다.
ssh -p 175 -o "ServerAliveInterval 10" -i /Users/mfd356/Documents/02\ -\ WEB\ personal/Electronics/Raspberry\ pi/ssh/privatekeyopenssh.txt [email protected]
외부 포트 175를 로컬 IP 192.168.0.175의 포트 175로 전달하는 규칙을 추가한 후 위 명령은 더 이상 연결되지 않습니다.
그러나 이제 외부 IP를 사용하는 동일한 명령이 제대로 작동합니다.
ssh -p 175 -o "ServerAliveInterval 10" -i /Users/mfd356/Documents/02\ -\ WEB\ personal/Electronics/Raspberry\ pi/ssh/privatekeyopenssh.txt pi@REDACTED_EXTERNAL_IP
이 -vvv플래그를 사용하여 디버깅할 때 포트를 전달한 후 로컬 IP로 ssh를 실행하려고 하면 다음 출력을 볼 수 있습니다.

-vvv하지만 출력에서 아무것도 얻을 수 없습니다 . /etc/ssh/sshd_config이것이 작동하도록 설정(예: 구성 파일)에서 아무것도 변경하지 않았기 때문에 이것은 나에게 이상합니다 . 라우터만 바뀌었을 뿐, 같은 브랜드의 라우터(현재 Sagemcom fast 3890, 이전 모델명이 기억나지 않음)이고 인터넷 제공업체도 같습니다.
어떤 아이디어가 있나요?
