Advanced network configuration for multiple guests

[corrafig]

Hi

I have four Linux guests and the host is also Linux. I would need:
1) Network connection between all guests
2) Host must have access to all guests
3) All individual guest must have access to host
4) Host have to have Internet connection

Optionally I would like also if:
5) Guests have access to Internet

Host machine have only one NIC and guests should be restricted so they can't disturb host machine's network connection to LAN and WAN.

Is this kind of setup even possible with Virtualbox? I've tried a lot of things. NAT would be the most suitable if guest machines could see each other.

With your current configuration you can add a second adapter to the guests as host-only .
Or switch to Bridged if you have a router.

Yeah! I was so focused to make it with only one NIC in guest... But now I have NAT (two way connection between guest and host) + Internet networkin (for guests).

Thanks
