OpenStack Single Node Internet problem

I am using VM to install Openstack ICEHOUSE Single Node setup, using a single NIC etho, by following [(https://fosskb.wordpress.com/2014/04/12/openstack-icehouse-on-ubuntu-12-04-lts-single-machine-setup/)] first of all my understanding about the Openstack Packet flow for a single node is:

VMs --> br-int --> br-eth1 [for vlans] -->br-ex [for external connectivity], is it right?

Then I have Edited file: /etc/network/interfaces

auto lo iface lo inet loopback

auto eth0 iface eth0 inet manual up ip address add 0/0 dev $IFACE up ip link set $IFACE up up ifconfig $IFACE promisc up ifconfig $IFACE multicast down ip link set $IFACE down

auto br-ex iface br-ex inet static address 10.3.1.145 netmask 255.255.255.0 network 10.3.1.0 broadcast 10.3.1.255 gateway 10.3.1.254 up ifconfig $IFACE promisc dns-nameservers 10.3.1.102

Defined networks [Flat and VLAN] in /etc/neutron/plugins/ml2/ml2_conf.ini, so [ml2] type_drivers=flat,vlan tenant_network_types=vlan,flat [ml2_type_flat] flat_networks=External [ml2_type_vlan] network_vlan_ranges=Intnet1:100:200 ..... [ovs] bridge_mappings=External:br-ex,Intnet1:br-eth1 ========================================= Created bridges and ports: ovs-vsctl add-br br-int ovs-vsctl add-br br-eth1 ovs-vsctl add-br br-ex ovs-vsctl add-port br-eth1 eth1 ovs-vsctl add-port br-ex eth0

Created Router, with 2 networks [Internal 10.3.11.0/24 and External 10.3.1.0/24 (with only 4 IPs in a row)] Now I can ping 10.3.11.0 --> 10.3.11.254 10.3.11.0 --> 10.3.1.216 [router's external interface] 10.3.11.0 --> 10.3.1.217-8 [Other Instance and Floating IP], and 10.3.1.145 its server IP But NO LUCK TO HIT 10.3.1.254

any suggestion or solution will be highly appreciable.
