Oracle Cloudでiptables-nftを設定

Last updated at Posted at 2022-12-31

iptablesの編集

  • /etc/iptables/ipv{4,6}を編集する
  • sudo iptables-restore < /etc/iptables/rules.v4
    • sudo /etc/init.d/netfilter-persistent reloadだと古いエントリーが消えてくれなかった
  • Dockerをインストールしている場合はDocker関係のエントリーが消えてしまうのでsudo service docker restart
    • snap install dockerでインストールすると、iptables-legacyを利用してしまうので、apt install docker.ioでインストールする
