Subject Re: Private and Public pool of IP Addresses
Date Fri, 26 Oct 2012 07:48:47 GMT
Hi, Charles.  This could be done on an "isolated" network in CloudStack,
but you need to manually set up the mapping after the VM is created.
You would configure a static NAT rule to essentially map a particular
public IP on the CloudStack-managed virtual router to a specific VM on
the private "guest" network behind the virtual router.

For "shared" networks in CloudStack, the VMs are not behind a virtual
router and are essentially on your network, so you could configure
CloudStack to assign public IPs directly to VMs.  You would have to make
sure your network could route the traffic.  You could also configure
CloudStack to assign private IPs and set up the NAT translation on your
own, outside of CloudStack.

Best regards,
