我正在运行 Ubuntu 20.04.3 服务器作为虚拟服务器。我的虚拟服务器使用 VMware 虚拟化，交付是自动的。我将设置为使用 outline，并且必须打开端口 443 和 8080。
我尝试在防火墙中执行此操作但仍然出现错误。
我们安装了docker程序，这是概要要求之一，并且该程序已启用，但由于未打开端口或破坏端口的问题，我们还无法使用该服务器。
我放置了显示我的服务器的网络配置文件和 ufw 信息的代码。
如果您需要更多信息，请告诉我。
你对解决这个问题有什么建议？
示例错误：
Host (myip) Port 8080
Testing...
Test assumes port 443 on (myip) refuses all requests
Your network does not block port 8080
**Port 8080 on Host (myip) is blocked by packet dropping or server is down**
Done!
Host (myip) Port 443
Testing...
Test assumes port 80 on (myip) refuses all requests
Your network does not block port 443
**Port 443 on host (myip) is blocked by packed dropping**
Done!
