Hi,

I followed the instructions on the [1] to configure RDO openstack with existing external network. When an instance is created , a private Ip is assigned and I manually assign a floating Ip. Everything went Ok.

However I can not access/ssh/ping instances using any of the Ips,

• Private Ip - 10.0.0.2
• Public Ip   -192.168.4.52

Routing table of the machine where RDO is installed.
[root@Openstack01 neutron(keystone_admin)]# route -n
Kernel IP routing table

0.0.0.0         192.168.4.254   0.0.0.0         UG    0      0        0 br-ex

How I created the subnet
neutron subnet-create public-udara 192.168.4.0/24 --name vlan --enable_dhcp=False --allocation_pool start=192.168.4.50,end=192.168.4.100 --gateway 192.168.4.254
