我跟了冰窖文檔安裝一個3節點環境 我OpenStack的節點都在CentOS的OpenStack的，中子，不能ping外網
http://docs.openstack.org/icehouse/install-guide/install/yum/content/basics-networking-neutron.html
建造，如同使用libvirt的虛擬機在我的網絡節點，外部NIC被配置不用其他IP按照文檔。（PROMISC = 「是」）
DEVICE="eth1"
TYPE="Ethernet"
ONBOOT="yes"
PROMISC="yes"
BOOTPROTO="none"
HWADDR="52:54:00:D3:92:E2"
UUID="7f8a9e99-fbd0-4c59-900f-2369c9e8f780"
然而，後增加網絡服務。 我無法在下面的階段ping外部網絡。 >外（外部geteway）
[[email protected] ~]# ping 192.168.125.254
PING 192.168.125.254 (192.168.125.254) 56(84) bytes of data.

From 192.168.125.54 icmp_seq=2 Destination Host Unreachable
From 192.168.125.54 icmp_seq=3 Destination Host Unreachable
2）外 - - >內部
[[email protected] ~]# ping 192.168.125.150
PING 192.168.125.150 (192.168.125.150) 56(84) bytes of data.
