Re: [Users] oVirt in PAT - NAT environment

Hi Assaf, thanks for the answer. the data center where my server reside is a server4you.net, so all what you get is a dedicated server and a public IP, thats it. You don´t have a "private" network via a NIC, the only access to the server is via the public IP. Ok, let´s try Neutron. Where can I find details on this? How to enable it and how to configure it? Anyone could also give me advices on how to setup the iptables on my server for correct DNAT and port forwarding to VMs? I would like to try boths. -Jarno ----- Ursprüngliche Mail ----- Von: "Assaf Muller" <amuller(a)redhat.com&gt; An: "relaxibus" <relaxibus(a)akfree.it&gt; CC: users(a)ovirt.org Gesendet: Montag, 10.

What you can do is either: 1) Define PAT on the data center edge router. For accessing VMS from the outside you can either define port forwarding or DNAT. As for reaching the VMs from your dedicated server, the easiest approach would be ensuring that the server has a leg in the private network. 2) You might want to try the oVirt Neutron integration. In Neutron you can create arbitrary private networks and VMs will get IPs from a DHCP server created in Neutron. You can then define a 'floating ip', which is a mapping between the VM's private IP and an allocated public IP on your public network. Neutron will do the DNAT for you. The oVirt Neutron integration in the recent 3.4 release [1] greatly improved the integration and it now includes IP address management, so you'll be able to do *nearly* everything from the oVirt GUI.
