ubuntu - UFW 规则被忽略

Question

如您在此处看到的，我已启用 ufw：

Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), allow (routed)
New profiles: skip

To                         Action      From
--                         ------      ----
22/tcp                     LIMIT IN    Anywhere                  
22/tcp (v6)                LIMIT IN    Anywhere (v6) 

出于某种原因，当我在端口 80 上启动 HTTP 服务器时，我能够查看网页，即使我没有设置允许端口 80 的规则。

当我试图拒绝端口 80 时：

Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), allow (routed)
New profiles: skip

To                         Action      From
--                         ------      ----
22/tcp                     LIMIT IN    Anywhere                  
80/tcp                     DENY IN     Anywhere                  
22/tcp (v6)                LIMIT IN    Anywhere (v6)             
80/tcp (v6)                DENY IN     Anywhere (v6)

我仍然能够查看网页。

有人可以告诉我我做错了什么吗？
