KVM 桥接连接不转发端口？

主机和客户机都是 CentOS 6。客户机有一个管理面板，监听端口 15672，我无法从外部访问。

来自嘉宾，curl localhost:15672并curl vm1:15672给我面板的预期内容。

我可以 ping 通它

# ping vm1
PING vm1 (10.2.8.72) 56(84) bytes of data.
64 bytes from 10.2.8.72: icmp_seq=1 ttl=64 time=0.087 ms

但无法访问面板。

# curl vm1:15672
curl: (7) couldn't connect to host

我按照给出的指示在本页当我到达时brctl show，我的输出与所显示的略有不同，但我不确定它是否相关。

# brctl show
bridge name  bridge id          STP enabled  interfaces
br0          8000.842b2b78ff80  no           em1
                                             vnet0
virbr0       8000.5254000ea9ec  yes          virbr0-nic

我确信你们都需要更多的信息来继续下去，但我想我对这个问题了解得不够。

我错过了什么？

答案1

问题最终是客户防火墙阻塞了应用程序端口，而不是 kvm 或桥接相关
