Hi Amit,

Have you tried specifying a name server with dig? Ie. dig domain.com @8.8.8.8 <—google DNS

Have you confirmed your instances have a resolver configured in /etc/resolv.conf? This usually occurs via DHCP.

I was hoping someone here maybe able to point me in the right direction. I have also posted the question at Ask, all the node stack details are here:

Hi all, So I cant seem to access the internet from my VMs. I can access the floating IPs from anywhere in our network and from all nodes now (controller/network/compute) just fine (but strangely I cannot access the private ips, the tenant network from any of the nodes?!) but cant ...
