Where I work we have a lan, it is almost 100% windows machines except for 2 CentOS machines in which some clients connect to, via VPN. (very small network, <50 ip's used)
I would like to know if there is a way to block access from that machines to others in the network.
I'm already logging traffic (with IPTraff) to see if they're accessing other machines in the network others than the ones they should connect.
Thanks in advance,
