Cannot ping external network gateway
I currently have a multi node installation of openstack grizzly running with Ubuntu 12.04 LTS. Quantum use case that i have used is "Per-tenant Routers with Private Networks".
I have one Cirros with two nic, one for private tenant network and one for ext_net.
Private network works but i cannot ping ext_net gateway (my public gateway).
Does anyone know why ?
