Hi Stackers,

I have a deployment environment based on openstack icehouse with 3 node architecture [ 1 compute + 1 controller + 1 neutron ]. Now I have 2 VMs running on compute node with default security group. I have got the VM IP in range of network assigned accordingly like private ip range of 123.0.0.x.

Now I would like to allow different IPs/udp traffic on same interface [ like 124.0.0.x ], but my security group doesn't allow me to do so. I have to manually flush all iptables rule which is obviously not a good way to do. Can anyone suggest how can we achieve this?
