I'm trying DevStack at the university lab. When I tried to deploy a VM I noticed that all the machines from the lab started renewing their leases with the DevStack DHCP server. That is inconvenient for me since I'm not the only user of this lab and it could cause troubles. I thought that perhaps changing the default port on the controller as on the compute nodes would work, but I don't know how to do that.</p>

I inadvertently did this once in our lab. The issue I believe (if my memory is correct) you're probably using nova-networking and you've configured FlatDHCP. The problem is that you're that your public network is accessing your internal/private network (check your bridge setting) so the result is that external DHCP requests can be received from your OpenStack private network.</div>
