Three VMs with CentOS 7 minimal created using VM Ware ESXI hypervisor: a controller node, a network controller node (Neutron) and a compute node (Nova). Things worked all right there as a test bed for PoC and lunching a few instances. That was OpenStack Newton.<o:p></o:p></p><p class="MsoNormal">Yesterday I followed the very same procedure and I ran into two problems: first problem was related to NTP, and I finally found a workaround for it. However the second problem I couldn't handle it so far and I hope to get some kind recommendations here. The problem is that it seems the traffic does not go off to the External network<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">I create an external network and a Router on a project using Horizon and connect the external network to the gateway of the Router. Everything seems fine, but I can't ping the router's gateway from my own client which are on the same subnet. It seems that External Bridge does not route the traffic outside.<o:p></o:p></p><p class="MsoNormal">I can't ping the router's gateway from Neutron server. With this big problem I can't go further, because instances won't be able to ping outside network, also they won't be reachable from outside.<o:p></o:p></p><p class="MsoNormal">I checked the firewall on my client and even turned it off. Also I checked Neutron server's firewall status using: "systemctl status firewalld" and service seemed dead.<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Here is my eth0 and External bridge configurations on Neutron server:<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">eth0:<o:p></o:p></p><p class="MsoNormal">DEVICETTYPE=ovs<o:p></o:p></p><p class="MsoNormal">TYPE=OVSPort<o:p></o:p></p><p class="MsoNormal">OVS_BRIDGE=br-ex<o:p></o:p></p><p class="MsoNormal">DEVICE=eth0<o:p></o:p></p><p class="MsoNormal">NAME=eth0<o:p></o:p></p><p class="MsoNormal">BOOTPROTO=none<o:p></o:p></p><p class="MsoNormal">ONBOOT=yes<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">External bridge:<o:p></o:p></p><p class="MsoNormal">TYPE=OVSBridge<o:p></o:p></p><p class="MsoNormal">DEVICE=br-ex<o:p></o:p></p><p class="MsoNormal">NAME=br-ex<o:p></o:p></p><p class="MsoNormal">BOOTPROTO=static<o:p></o:p></p><p class="MsoNormal">DEVICETYPE=ovs<o:p></o:p></p><p class="MsoNormal">ONBOOT=yes<o:p></o:p></p><p class="MsoNormal">IPADDR=172.16.10.123 <o:p></o:p></p><p class="MsoNormal">NETMASK=255.255.255.0<o:p></o:p></p><p class="MsoNormal">GATEWAY=172.16.10.1<o:p></o:p></p><p class="MsoNormal">DNS1=8.8.8.8<o:p></o:p></p><p class="MsoNormal">PEERDNS=yes<o:p></o:p></p><p class="MsoNormal">USERCTL=yes<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Even I lunched three instances using Cirros image and they able to ping each other, also able to ping the gateway of the router, However nothing seems reachable from outside.<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">That's why I think there should be something wrong with External Bridge.<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Please Help, if you have any alternative config for external bridge and NIC card, or whatever useful to help my limit knowledge...<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Thank you<o:p></o:p></p><p class="MsoNormal">Rez<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">P.S: Is the NIC card type in VM has anything to do with this problem? I mean when I created the Virtual machines, I chose VMXNET3 as NIC card type, should I try another type, something like E1000, maybe for compatibility?<o:p></o:p></p></div>
