We are running a Hyper-V server on our Windows Server 2008 R2. I have ordered a subnet because we would like to provide each of your VM's with a public IP address.
My data center provider (Hetzner AG from germany) writes the following about it:
Problems with virtualization
With this type of IP/subnet allocation, it is not possible to use a "bridged" setup, as with such a setup several MAC addresses appear. VPS (linux virtual servers, Xen, vmware, etc) must use a so-called "Routed" setup (VMware: "host-only networking"). With an additional subnet the host system or dom0 must be configured with an IP address from the subnet which is then used as a gatewar for the VPS. The (additional) address of the host system must therefore be configured in the VPS in each case as a gateway. An exception to this rule is "openvz", which does not require a gateway. On the host system or dom0 "ip_forward" must be activated for each virtualization:
Well, what does this mean for me now, how do I have to configure hyper V?
Thanks for your help!
