iptables는 Debian을 다시 시작한 후 새 규칙을 복원하지 않습니다.

아래와 비슷한 질문을 많이 시도했는데, 제 경우에는 VM을 사용했습니다.데비안 운영 체제존재하다가상 상자:

1. https://serverfault.com/questions/129086/how-to-start-stop-iptables-on-ubuntu
2. Debian 시스템을 다시 시작한 후 iptables 규칙이 사라지는 이유는 무엇입니까?
3. https://www.digitalocean.com/community/tutorials/how-to-list-and-delete-iptables-firewall-rules
4. https://www.digitalocean.com/community/tutorials/how-to-set-up-a-firewall-using-iptables-on-ubuntu-14-04

iptables다음 명령을 사용하여 규칙을 새로 고치 려고 했습니다 .

sudo iptables -P INPUT ACCEPT
sudo iptables -P FORWARD ACCEPT
sudo iptables -P OUTPUT ACCEPT

다음은 다음 명령입니다.

sudo iptables -t nat -F
sudo iptables -t mangle -F
sudo iptables -F
sudo iptables -X

나는 이전에 시도했습니다:

iptables-save > /etc/iptables/rules.v4
iptables-save > /etc/iptables/rules.v6

머신을 재부팅했을 때 다시 이전 규칙으로 돌아갔습니다. 여전히 동일한 규칙이 있습니다. 을(를 ) 사용해 보았 iptables-save더니 이러한 메시지가 표시되었습니다.

제가 원하는 것은 아래와 같은 규칙입니다. 내 명령을 다음과 같이 설정했습니다 rules.v4.

하지만 시스템을 다시 시작할 때마다 항상 이전 규칙이 표시됩니다.

내 구성에 어떤 문제가 있을 수 있나요? 내가 뭐 놓친 거 없니?

제거하고 다시 설치해 보았 iptables-persistent으나 여전히 동일한 규칙이 나타납니다...
