[Openstack] Weird ping problem

Hi all,

I now have a nicely stable OpenStack install running on five servers, with one acting as control with all the services, and the rest just compute/network nodes.

The strange thing now, is that if an instance is running on the control node, it can ping the outside world, but if it's running on any other node, it can't ping the outside world, even on the LAN. The odd thing is, it *does* successfully do a dns lookup. Additionally, it can ping other instances on the private network address range.

Any ideas?

Thanks
