How to forward all ports from VirtualBox to a subdomain?

Question

Domain Name System

There is a server under Windows, on it is a virtual machine with debian.
Is it possible to somehow redirect all connections to a subdomain like server1.site.ru
Here I tried to forward ports, but it doesn’t work to enter the lines there.

You need to forward ports in the range 1-35000, so that the virtulka responds only to server1.site.ru
and Windows responds to site.ru

Of course, you just need to set up port forwarding.

Of course, because the IP address consists of numbers.

Nobody responds to anything. A host can be accessed either by IP address or by a name that resolves to an IP address. Ports here are generally not important in any way, and do not matter.

Answer 2

Make a network bridge in the network settings of the virtual machine. And you won't need to do any forwarding.
