Internet connection sharing( a Linux internet gateway)
 

Hello Folks.
How are you?
I want to lunch a Linux gateway and I need your advice. I have some windows clients and I want to launch a Linux internet gateway to share internet to specific users, block some users and so on. Any idea?
Which distro is better for it? I guess OpenSuse have an option for the gateway.
If possible, Please advice me, Step by step.

Thank you so much.

Is it enough? I guess it is a little more complex than it.
I want to ban some IP address and allow someone.
