> If you want Linux to use a firewall then install one into it

Granted, I don't know much about WSL, but that's a very surprising model to me. I would naively assume that anything in userspace is controlled by the Windows OS-level firewall, not that Linux gets to emit raw packets. To say the least, I'm a little more hesitant than you are to call that reasonable.

As mentioned other places int the article, in the WSL2 model, Linux is running under a Hyper-V hypervisor, and isn't in user space.
