Running a Windows VM on KVM, how do I restrict network access to specific applications instead of the entire OS? (lemmy.world)

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!

You’ll have to accomplish that with a firewall on the OS. A network firewall could restrict traffic based on ports, but your apps aren’t that predictable.

I see, I don't have a choice then. I will only really access the internet using Firefox, whilst the file explorer will be allowed to map a network drive on my LAN.

This is an issue that I've been thinking of but can't come up with anything!

That's... What firewall is for

Yes, well, I was hoping I could do this from the linux side instead of configuring the Windows firewall, but apparently not

If you are finding using windows FW hard, you could try https://github.com/pylorak/TinyWall

Thank you, I'll bookmark this! Another commenter pointed out SimpleWall, need to check that out too!

The reverse is easy, maybe consider hosting the apps as containers?

There might be Windows-specific software that might not run with WINE, which is why I'm considering this option
