檢查 ufw 預設策略操作

  • May 9, 2019

我知道設置 ufw 的預設行為非常容易,例如ufw default deny,但是如何檢查預設的 POLICY 操作是什麼?它沒有顯示在ufw status.

嘗試ufw status verbose

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

現在我將其更改為允許:

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

相應地反映狀態,預設已更改為允許:

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