Sharing a friend's internet through a vpn server?

Question

Computer networks

Hello dear. A question. I recently bought an apartment in a new building, I need to connect to the Internet. As a new house, the choice was not great. I called several providers, settled on a provider to which a friend was just connected. But the prices for the tariffs are a bit unsatisfactory, and because of my cunning ass, I want to know. Is it possible to connect two routers in the same network (from the same provider), which are located at different addresses (city addresses, respectively). Let's say there is a router A that is connected to the Internet and has paid the most expensive tariff with high speed. And there is a router B that is connected to the same provider, but the tariff is not paid, respectively, access is only to the internal resources of the provider. You need to connect from router B to router A and get a friend's fast internet.
I googled a little and thought - why not raise the vpn on a friend's router and connect directly to his vpn and not to the provider. Is it real?
Thanks in advance for your replies!

Answer 1

logical routing
- if subscribers are allowed to use internal resources, and even StrongDC is connected anywhere - really
try ping on your friend's IP, well, or immediately
put a VPN or proxy on his computer
, but usually it will check subscriber-to-subscriber traffic, just so that they don’t scan

Answer 2

Yes really. In this case, even a VPN is not particularly needed - just configure the default route through a friend's router.

Answer 3

Technically, it's possible. In practice - I'm telling you as a provider - the provider will be offended by this;) Yes, and you can block it in principle ....

Answer 4

You won't get anything. Any sane administrator at the provider forbids GRE on the locale.
