title: OpenStack - How to add multiples Floating IP in the same port
body: <p>How can I to add two Floating IP(Public) in the same port(interface)? It's Possible?</p>
  <p>Example(Port - Eth0):
  eth0 - 192.168.1.10 - Public IP 01
  eth0:1 - 192.168.1.11 - Public IP 02</p>
  <p>** Currently, I can do this only if I add another port(eth1), but it's not resolve my problem because my mailserver(cpanel) accepts adding a second IP only if it is associated with the main interface(eth0).</p>
