I've followed the Mitaka setup guide for my first OpenStack cloud. This all went ok (2nd time around!), however i'm now having issues with networking. The instance launches ok, and it's assigned an IP via DHCP, but it won't ping. I don't know if my network is setup right, so i've provided the appropriate outputs below.

I setup Mitaka with option 2 - 'self service networks', but for simplicity i've only created a Flat DHCP 'provider' network just to get a feel for things. On my test setup I only have 1 working public IP address, x.x.x.111
