检查 ufw 默认策略操作

Question

我知道设置 ufw 的默认行为非常容易，例如ufw default deny，但是我如何检查默认的 POLICY 操作是什么？它不显示在ufw status.

Answer 1

尝试ufw status verbose：

root@cmp:~# ufw status verbose
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), disabled (routed)
New profiles: skip

现在我将其更改为允许：

root@cmp:~# ufw default allow
Default incoming policy changed to 'allow'
(be sure to update your rules accordingly)

状态会相应地反映出来，默认值已更改为允许：

root@cmp:~# ufw status verbose
Status: active
Logging: on (low)
Default: allow (incoming), allow (outgoing), disabled (routed)
New profiles: skip
