Angry iptables line


Hi

This is a newbie question.

I've got a linux server and have some pcs in my lab,
I would like to set a line with iptables command
that drops the internet to all the pcs in the lab except one.

is it like this ?

iptables -A INPUT -s ! pc with internet -p tcp -j DROP

thanks for your answers



Aaron

Do the lab PCs connect through the server to the internet (ie: the server is a gateway)? If so, try
Code:
iptables -A FORWARD -i eth? -s !pc -j REJECT
Replace the ? with the correct number of the interface that is connected to the lab.
