[one-users] How to connect to VMs

[Jaime Melis]

Hi Johannes,

yes that's exactly the recommended way of doing it. Typically there is a
"gateway" vm which has two interfaces, one in a reachable network: Public
IP or  in the network of your hosts, and another one in the specific
network (usually isolated) to your vms. The other vms have a single
interface in the private network of your vms.

cheers,
Jaime
