Hi, good morning!
From what I understand..
Not attached.. Network card emulated, but not connected
NAT.. The emulated network card can use your network connection, but is located behind the VM software's router/bridge/hub
NAT Network.. Similar to above. The VM software uses your network connection, but multiple VMs are connected through the same translation mechanism (NAT). They can access the outside world and see each other, too. They are hidden behind the VM software's router/bridge/hub
Bridged Adapter.. The emulated network card takes possession of your real network card (bypasses the PC's OS and its firewall)
Internal Network.. The VM software provides a network environment that exists among VMs only, no data flows from/to the real world
Host-only Adapter.. The VM's network card can talk to your local PC only?
Generic Driver.. The VM uses a driver to talk to the outside world, instead of emulating a particular network card model?
Edit : Hope that helps. I'd go with NAT first, it's the most hassle free, I guess.
Or NAT Network, if you're using multiple VMs at once.
A special case might be multi-player gaming, in which both parties need to know each other's IP address.
Edit : I'm sorry. Just realized what you want to do.
Choose NAT Network, if you want to get online with the VMs.
Or try Bridged, if that doesn't work.
