Instance cannot reach internet or Openstack DHCP services

 

Hi Openers,

I finally deployed an instance with a NIC attached by now I am affraid I have a Networking miss-configuration, because the instance cannot reach the internet nor the Openstack DHCP services.
I tried stopping the firewall, giving a static IP, etc but I cannot ping anything.

My networking looks like this. Can anyone find what is wrong with this?
 

1. Public Network 
Subnet 192.168.100.0/24

Gateway: 192.168.100.254
-Ports-
network:dhcp   IP: 192.168.100.51Status: ACTIVE

network:router_gatewayIP: 192.168.100.50Status: DOWN

network:floatingip     IP: 192.168.100.52Status: DOWN


2. Private Network
Subnet:172.30.10.0/254
Gateway:172.30.10.1
-Ports-
network:dhcpIP: 172.30.10.2Status: ACTIVE

network:router_gatewayIP: 172.30.10.1Status: ACTIVE

compute:None     IP: 172.30.10.3Status: ACTIVE----My instance`s IP address

3. Router
Interface 1: 192.168.100.50External GatewayStatus: ACTIVE
Interface 2: 172.30.10.1Internal InterfaceStatus: DOWN

My Openstack single node server network info is:

1. Public IP (internet access)
eth1:
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=none
DEVICETYPE=ovs
TYPE=OVSPort

OVS_BRIDGE=br-ex

br-ex:
DEVICE=br-ex
ONBOOT=yes
BOOTPROTO=static
DEVICETYPE=ovs
IPADDR=192.168.100.24
NETMASK=255.255.255.0
TYPE=OVSBridge
GATEWAY=192.168.100.254


2. Management IP (no internet access)
eth0: 
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=10.3.7.24
NETMASK=255.0.0.0
NETWORK=10.0.0.0
BROADCAST=10.255.255.255
