私はSSHを使用しており、しばらくそれをやってきました。新しい場所に移動し、新しいルーターを購入しました。これで、ローカルIPを介してのみsshを使用できます。以前にSSHを介した外部アクセス用にポート転送を設定した場合、ローカルIPは機能しなくなります。
たとえば、1台のマシンでは、次のコマンド(Raspberry Piに接続)が正しく機能します。
ssh -p 175 -o "ServerAliveInterval 10" -i /Users/mfd356/Documents/02\ -\ WEB\ personal/Electronics/Raspberry\ pi/ssh/privatekeyopenssh.txt [email protected]
外部ポート175をローカルIP 192.168.0.175のポート175に転送するルールを追加した後、上記のコマンドは接続されなくなりました。
ただし、外部 IP を使用するのと同じコマンドが正常に動作します。
ssh -p 175 -o "ServerAliveInterval 10" -i /Users/mfd356/Documents/02\ -\ WEB\ personal/Electronics/Raspberry\ pi/ssh/privatekeyopenssh.txt pi@REDACTED_EXTERNAL_IP
この-vvv
フラグを使用してデバッグするときにポートを転送した後にローカルIPでsshを実行しようとすると、次の出力が表示されます。

しかし、出力から何も取得できません。/etc/ssh/sshd_config
これが機能するように設定(設定ファイルなど)で何も変更していないため、これは私にとって奇妙です。ルーターだけが変わっただけで、同じブランドのルーター(現在Sagemcom fast 3890、以前のモデル名が覚えていない)であり、インターネットプロバイダも同じです。
どんなアイデアがありますか?
