[Openstack] [PackStack][Neutron] How to configure for external network


For external network You should use flat or vlan type - which one of them, depends on Your providerâ??s configuration - if You should use some VLAN, You need vlan network.
Vxlan networks can be only used for tenant networks.

> Hi,
> I installed PackStack on two nodes, one as Controller and Network, the other as the Compute Node. After installation, I created a new br-ex interface and I did OVS settings. I also define two internal and external network (flat) and router and interfaces. 
> The internal network range IP is not a valid range and for the test, I set it in I can lunch instances using internal network and VMs can connect to each other using that.
> The external range IP is the same as our Provider range IP (the range that our devices get when connecting to the internet). But lunching instances using the external network it can't connect to the internet or ping other devices in the network (proper security groups are set). IMy question was, is there any tutorial for configuring the network in two nodes so VMs can connect to the internet? What kind of Network does it need? flat, vlan or vxlan?
