現状は /etc/ufw/user.rules にある。ブートでも反映される。

UFW設定でミスして、締め出された場合にはコンソールから入るという手があるか。

簡単設定では 「DNS port を開くには packet filter を全開放する」 選択しかなかった。

この選択をやめられた。API で設定できたから。-- ToshinoriMaeno 2023-04-02 21:50:55

default deny

nuro IP address が変わったときにも入れるようにするには: {39.110.135.0/24 ?}

a.ns.qmail.jp から入れるようにしておけば、tssさんにお願いすればなんとかなるだろう。-- ToshinoriMaeno 2023-04-02 22:08:38
