I'm currently using 5 public IPV4 addresses on a physical machine running Ubuntu Server, which I intend to replace with new hardware running Proxmox.
I'll do a P2V of the current Ubuntu install into a VM on the new one. I'll then need to replicate the networking on that guest, which currently looks like this:
auto lo iface lo inet loopback auto eth0 iface eth0 inet static address xx.xx.40.154 netmask 255.255.255.0 network xx.xx.40.0 broadcast xx.xx.40.255 gateway xx.xx.40.1 auto eth0:0 iface eth0:0 inet static address xx.xx.40.155 netmask 255.255.255.0 auto eth0:1 iface eth0:1 inet static address xx.xx.40.156 netmask 255.255.255.0
How should I configure things to work so that the VM is visible on its public IP addresses as it was then it was on the physical machine?
Right now, the default networking interfaces on the Proxmox host look like this:
auto lo iface lo inet loopback iface eth0 inet manual auto vmbr0 iface vmbr0 inet static address 192.168.10.2 netmask 255.255.255.0 gateway 192.168.10.1 bridge_ports eth0 bridge_stp off bridge_fd 0
I get the feeling that's not going to work though, but for some reason I can't find any guides to this. I'm not using a firewall or any other complications here.
