<div dir="ltr"><div><div><div>Hi Sam:<br><br>I believe this is doable if you're using Neutron for networking. You would need to set up two Neutron "external" networks, one that contains the subnet with external, routable IPs, and the other that contains the subnet that is routable to your internal services.<br>
<br></div>Last time I checked, Neutron only supported one external network per network controller (this is a limit of the L3 agent implementation). This means you'll have to set up two separate network controller nodes with L3 agents, one that has a network connection to your external network, and the other that had the network connection to your internal network.<br>
<br></div>It's up to you whether you want your OpenStack instances to connect directly to these networks, or if you want to use internal OpenStack networks and use floating IPs. Either way, when you boot your instances, you need to specify that you want the instances to be connected to both networks. Your instances will then come up with two virtual NICs.<br>
<br></div><div>Hope this helps. Good luck!<br></div><div><br></div>Take care,<br><br>Lorin<br><div><div><div><div><div><br></div></div></div></div></div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Thu, Dec 5, 2013 at 10:02 AM, Samuel Winchenbach <span dir="ltr"><<a href="mailto:swinchen@gmail.com" target="_blank">swinchen@gmail.com</a>></span> wrote:<br>

Is there a good way to have VMs access both an external and internal network? We would like set up several VMs that have external, route-able IPs but also have access to our internal network for some of internal services (e.g. NFS).</div>
