I am trying to setup open stack on Ubuntu 14.04 following (Three-node architecture) with Open Stack Networking on three physical machines each having more than two NIC cards , i assigned the ip address as given in the documentation but i am stuck at Verify connectivity part since i am unable to connect to internet if i use the management network vice versa , how to rectify this problem. i used two switches one for connecting Management interfaces and another one for Instance Tunnels will that be sufficient or do i need to have a router between interfaces ?.
