I have a dedicated server, one main public IP from /27 and two single public IPs also from the same /27 (I think the provider manages single IPs using the VLAN tags).
I want to have a KVM running on the server and two VMs on the KVM. I would like not to use NAT or Bridge model, but setting a KVM Host as router, so I can access the VMs from the Internet.
It should look like here:
I found two different tutorials one saying
auto eth0 iface eth0 inet !!manual!! auto br0 iface br0 inet static address x.x.x.x pointtopoint x.x.x.1 gw x.x.x.1 bridge_ports !!eth0!! ...
and another saying:
auto eth0 iface eth0 inet !!static!! address x.x.x.x pointtopoint x.x.x.1 gw x.x.x.1 auto br0 iface br0 inet static address x.x.x.x pointtopoint x.x.x.1 gw x.x.x.1 bridge_ports !!none!! ...
It is very confusing, considering that none of them working.
What are the differences of combining manual with bridge_ports eth0 and static with bridge_ports none?
