  • Block traffic

    I have a computer in my lab that I want to limit all network traffic to/from.
    I want it to be able to communicate only on the local network
    (e.g. allow only a certain range of IP addresses to communicate with
    it) and block everything else. I don't even want to allow any web
    browsing on the computer... Is there a way to do this with normal
    Windows firewall or some other free firewall?

    No, Windows Firewall doesn't filter outbound connections.

    Would expect so, yes.

      You could try removing the default gateway from the machine if all the IP's are on the same subnet.

        Methinks IPSec policies could also do the trick, although that's not the most simplistic solution. For some inspiration you could read:
