![80端口连接被拒绝](https://linux22.com/image/942052/80%E7%AB%AF%E5%8F%A3%E8%BF%9E%E6%8E%A5%E8%A2%AB%E6%8B%92%E7%BB%9D.png)
我是 Ubuntu 防火墙的新手,我有 Ubuntu 20.04 服务器。
所有端口 8080、81... 都是对外开放的,但是当我尝试时,telnet IP 80
我收到了
telnet: Unable to connect to remote host: Connection refused
ufw status verbose
是:
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), deny (routed)
New profiles: skip

类似的问题有助于我扩展有关该主题的知识:

最后一个链接指导如何重新启动 iptables,但我希望我错过了其他内容,而我不必重新启动 iptables。
请指导我在这种情况下该怎么做,以及如何通过端口 80 接收对我的主机的公共访问。
非常感谢您的支持。
