How to set up a separate internet for each Windows account?

Question

Computer networks

I have three providers (three physical cables). Can I use native Windows tools to set up routing in such a way that each account uses only "its own" network card? Moreover, it is important that if the network is not available through "one's own" network card, then the "foreign" network card should not be used. That is, the account should see only one, its network card.

If this cannot be done using Windows, then maybe there is reliable software for such a task?

It is important for me that each account would always go online through "its" provider.

Answer 1

Hmm vpn connection for each account and autologin checkbox. But why 3??? Usually they do 2 to make stability, 3, well, except perhaps for the comments of the bank.

Answer 2

There are two options for solving this problem.
Simply put, this is a VPN, i.e. there is a network allowed for everyone, after loading the user raises his VPN with his settings and works already through the VPN connection.
By adding 802.11x, after login, the user is authenticated on the radius server, which the advising VLAN issues to the network port.

Answer 3

A script of some kind, at startup, prescribing routes and disabling extra cards ...
Another thing is what kind of rights the users have there and what kind of users themselves

Answer 4

But what if:
1) set up a separate PPPoE server on the router for each provider?
2) On each server, create one account - for the user who must access the network through this provider
3) on the client machine, create a separate PPPoE connection for each profile, prohibiting its use by other users?
It turns out that there is no Internet "by cable" and each user, in order to access the network, must log in through the PPPoE that is available to him.
Will this work for "native" provider differentiation between windows accounts?
