title: Multiple outbound IPs on a single GCE instance
body: <p>I need multiple outbound IP addresses for my Compute Engine VM to choose from for outgoing requests.
  Is there an easier way then creating multiple networks and NICs?</p>
  <p>I thought about Cloud NAT, but with multiple IPs assigned to the NAT, it always selects the same IP for every outgoing request. I need a way to select which IP is used for each request. Any suggestions?</p>
