Best way to disable internet access?

Cody John

I have a lab of computers that I want to disable internet
access. I run a Novell 4x network, so my first thought
was to disable tcp/ip. Well that worked until i realized
that the Master Vision software we use in the lab relies
on tcp/ip. So my solution was to go into each computers
Local Security Policy and use 127.0.0.1 as the proxy
server address at port 20 just for redundancy. This has
worked so far but was just wondering if there is a more
straight-forward fix.

One way would be to disable outbound access for these computers by their IP
address at the firewall, which would require that their addresses be static or
within a scope of computers denied access. Another way would be to configure
them to have no or wrong default gateway. --- Steve

Block them in your firewall.

You could put all the lab machines into an OU and
use a GPO to control this. You could umplug the Lab
from the net, or filter the lab adresses at your router.
