Is it possible to raise proxification on a VIRTUALBOX virtual machine installed on a dedicated server?

Question

virtual box

There is a dedik with 4 cores and 8 gigs of RAM.
Several ipv4 + 1 ipv6 go to it.
Hosters routed an ipv6 /48 subnet to this ipv6.
If I put virtualbox on the dedicated server and write ipv6. Then the subnet will also be "routed" to this ipv6 inside the Virtual Machine?
Will I be able to proxify inside the virtual machine to selected addresses from my subnet?

Answer 1

You can do anything if you know how. In the end, virtual machines in this regard are no different from real ones, and virtual network interfaces from real network cards.
Regarding the second question... nothing itself will be routed anywhere. Each machine needs to somehow pass information about its address, mask, gateway and additional routes.

Answer 2

Maybe it's worth poshamanit at the router level? (Of course, all VMs must have a network bridge enabled)
