How to access the Internet under different accounts + different connections from one computer?

Question

Computer networks

Is it possible to make "two/three/four.. Internet access" on one computer in different accounts?
independent of each other and not interfering with each other?

the task is to take a computer, create 3 accounts in it and connect each one to your Internet via a USB modem (BEELINE, MTS, MEGAFON)

in order to simultaneously sit in each account "from your modem" and so that each account has its own Internet connection.

Answer 1

Can.
But it is much easier not to suffer with three modems, but to rent several proxies, and release each user through his own proxy.

Answer 2

you can do it directly and simply through virtual machines.
if native then IMHO there will be a lot of drochev with the distribution of packages.

Answer 3

Autoload script that will switch network connections depending on which user is sitting at the PC
