You should configure networking on the VMs as if they were real servers; 
there's no general answer. Depending on your requirements, you may need 
to have both public ad internal IP addresses on the same machine, 
isolate VMs on a network that is completely separate from the Proxmox 
servers and/or your LAN, have a (virtual, maybe) firewall filtering and 
redirecting connections to the VM, or something completely different: 
there are so many possible configurations that it would take a book just 
to enumerate them.

That is, if you have any doubts, ask your local network administrator. 
Your question doesn't have much to do with the fact that your servers 
are virtual, except maybe for the added benefit that you can create and 
destroy network adapters at the touch of a button.
