Stopping a user from internet access?

[hankach]

Hi all ,

Any simple way to block a network pc connected to a server to stop accessing internet without affecting the other connection with the server ?

How to do that step by step?

Thank you much for your help !

Hello,
Operating systems?
Does the server run any sort of firewall?
Do you want to block a particular user or a particular pc?
