Is it possible to access the Internet through another client in the provider's local area?

Question

openvpn

Essence. There are two different clients connected to the same provider with different tariff plans.
Let's say the 1st is connected via ADSL with Internet access at a speed of 1Mbps, and to the provider's local network at a speed of 8Mbps.
The 2nd is connected via GPON with a speed of 30Mbps to the Internet and 100Mbps in the local area.
The provider's network has an Openvpn server, when connected to which both clients are on the same network.
Question. Is it possible for the 1st client to access the Internet through the 2nd client, i.e. at 8Mbps? It is clear that you will need to install at least 1 router on the side of 2 clients. How to set it up?

Answer 1

Yes, you can do it without a router. Start a proxy on a fast client, and a slow one will connect to this proxy via IP.
Another option - if without OpenVPN clients see each other via internal IP, you can raise an OpenVPN server on a fast one, to which a slow one will connect.

Answer 2

I remember that I solved a similar problem a long time ago, by logging in to a PC with fast unlimited internet through the provider's internal system))

Answer 3

I don’t know how right now, but about 10 years ago we distributed the Internet in this way on the local network .. On the distributor, in the settings of the network card, on (TCP / IP) - Properties - Advanced - uncheck the use the main gateway ..
And the usergate program was needed , in its settings, in the "local servers" tab, add an asterisk *, and in the http and socks5 points, for example, ports 3128 and 1080, respectively
. it and prescribe the local IP of the distributor and the port ..
Everything, only IP if the dynamo, they must somehow be transferred to clients during updates
