I triyed many different configurations, but no way.

Hope someone here would be able to help me.
Thank you in advance for your time !

So, if I understand your issue, your proxmox server is a virtualbox vm, and the proxmox server has an internet connection, but the vms you create in your virtualized proxmox instance do not have an internet connection. IS that accurate?
