Is it possible to set up a client and a server on the same computer to receive traffic from the provider through them?

Question

Computer networks

Or does the operator's network have a higher priority than the laptop that is its client and receives distribution from this network? Is it possible to organize a subnet to filter traffic?

Answer 1

What client and server?
Let's better without terminology, in which you still don't understand very well.
As far as you can understand anything from your question, you want to organize and delimit access to the network, where the laptop is a kind of "gateway"
Let's get on the fingers, what do you want to get in the end?
