My setup is:
-
在无头设备（主机）上运行的Ubuntu服务器16.04
-
在主机顶部运行的Windows Server 2016 KVM（guest） .
-
主机和来宾之间的网络类型是NAT . 整个事情都在公司背后 . 代理 .
-
主机从公司网关获取静态IP .
在KVM上，我正在运行从内部和外部侦听端口15417的docker容器应用程序（docker ps：0.0.0.0：15417 - > 15417 / tcp）容器IP地址为192.168.122.35，而KVM IP地址来自NAT是：192.168.122.82
在docker容器上运行的应用程序正在公开一个API，应该从kvm_ip上的linux主机访问：15417 / api
The facts:
-
在Windows FW上打开端口15417以进行入站TCP连接 .
-
从主机到kvm IP有一个有效的ping（192.168.122.82）
-
可以在192.168.122.35:15417/api上访问app api
-
泊坞窗日志，显示日志，以便应用程序启动并运行 .
The problems:
- 无法从localhost：15417 / api或127.0.0.1:15417/api上的KVM访问API，我得到的
curl localhost:15417/api的响应是：
目标主机无法访问
-
无法从主机上的192.168.122.82:15417/api(KVM_IP）访问API，
curl 192.168.122.82:15417/api上的响应与kvm powershell上的响应相同 . -
没有telnet到192.168.122.82 15417来自主机或telnet 127.0.0.1 15417来自guest，而telnet到其他端口如RDP（3389）或vnc（5900）工作正常，这意味着端口全部打开 .
这是我的主人'ifconfig'：

我的KVM（来宾）网络默认配置：

最后KVM网络接口配置是：

<address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>

我在试图找出什么是打断时挣扎，我从主机上访问KVM上的应用程序 .
