Controlling Internet access

By jr.callan ·
I want to be able to restrict internet access to students in a classroom while allowing others in other areas access.
Internet access is via router. The server, and other users are linked via switch. The classroom has its switch which is in turn linked to the switch with server and other users. See crude diagram below. How can I restrict the Internet to the classroom while still allowing it access the server?

Physical switch?

by jr.callan In reply to Access list on the Router

Thanks Chris and sorry for the way the diagram turned out in the original post.

What I really want is a way of physically switching on/off access to a group of clients, students in a school classrom. I wondered whether a second network card on the server would do but not sure how this could be setup.

Problem is that with one server, one router all patched into various switches, they cann all see the gateway. It would be nice to have a physical on/off switch to isolate certain groups.
