Hi everyone,

Is there any way to restrict network access for a Windows VM using KVM other than a couple of applications (Windows explorer and Firefox)? I don’t want to get into configuring the Windows firewall and would like to do this using KVM/other linux utilities on the host machine if possible As I thought, it is unlikely that I will be able to do this from the KVM side of things. Would anyone have an idea of how I could script this for subsequent Windows VMs?

Thanks!

    With that said, can I possibly only allow traffic to and fro from the proxy through my firewall?

    Yes. That is what I suggested. If you configure the firewall to only allow traffic to/from the specific IP and port combination of your proxy, other traffic will be blocked.

    I should be able to (in theory) inspect traffic too, although I don’t know how far that will take me.

    You can do content filtering via a proxy like that, yes. A similar sort of configuration is used on school computers to do things like block adult content, with varying degrees of success. Some ad-blocking techniques work on similar principles.

      I was wondering if I could label the traffic to and from the proxy, and not have to rely on ports for filtering

        You can whitelist both the proxy and the ip, blacklist everything else.
