title: GCE Managed Instance Group - static IP address for outbound server requests
body: <p>Is it possible to set up a static IP address or range of IPs for server requests to external dbs and web services?</p>
  
  <p>We have a web app running on Google Compute Engine managed instance group. We want to lock down access to our db to specific IP addresses. However the server IPs on the managed instance group are stateless, and the IPs change with each update to the web app. Is it possible to assign a static IP/range of IPs to our outbound server traffic?</p>
  
  <p>We've investigated NAT Gateways, and VPC Peering a bit, but it doesn't seem to exactly fit our requirements. It's kind of a 'load-balancer for outbound server traffic' or something that would seem to fit what we're looking for... </p>
  
  <p>Any advice greatly appreciated.</p>
