Hi Janis,<div><br></div><div>If your provider network maps directly to a publicly accessible network then you should be able to assign IPs to VMs from a public range without using Floating IPs and NAT.</div><div>With Quantum, you just specify a physical network (e.g.: eth0) and a segmentation id (e.g.: vlan id 999) for creating this mapping; ensuring it actually results in VM instances directly connected to a public network is beyond the scope of Quantum.</div>

</div></div>Not right now. With Quantum, a router can only uplink to a single<br>
external network, and you can have at most one floating IP per<br>
external network (otherwise we could not unambiguously apply the<br>
policy of SNAT-ing VM initiated connections to the floating IP). In<br>
Grizzly, we're planning on making router uplinks more sophisticated,<br>
which will include not only the ability to uplink to multiple networks<br>
with floating IPs, but also uplink to other types of connectivity,<br>
such as an external VPN.<br>
<br>
I'll update the admin guide to make this clear.<br>
