[Rdo-list] Can't access instances created - RDO with external network

[Udara Liyanage]

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 at Openstack01 neutron(keystone_admin)]# route -n

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
