How to proxy multiple guest OS (VirtualBox/VMware) from main system?

Question

virtual box

It is necessary to create 2-10 virtual machines with Windows 7.
For each machine, assign a separate proxy server (ipv4 / mobile), through proxyfier or similar software, as a proxy with a password and login. So that each virtual machine has a different external IP.

I tried to proxy a file with VirtualBox through ProxyFier right away, but this will work only if one virtual machine is available, that is, if you run two or three, they will have the same external IP, since the Internet in VirtualBox controls 1 process, as well as the launch of machines .

Proxying in the guest system will not work, you need it from the outside, i.e. from the main one. How can something like this be implemented? Thanks in advance for your reply.

Answer 1

Check out VMware. It can set its own network settings for each VM.

Answer 2

On the main system, raise the local proxy servers intermediaries (on unique ports)
I advise 3proxy (parent option)
in guest systems in the ProxyFier config you specify local proxy intermediaries
with the current method, you can change target proxies on the fly (by changing the 3proxy configuration)
