Well - since WSL2 provides the ability to access ports on the machine
*inside* WSL2 as 127.0.0.1 from the *host*, this is the expected behaviour.

If you don't like this - don't use WSL2 but instead Hyper-V only with a
"real" virtual machine inside Hyper-V and a virtual network setup for
Hyper-V which is shared with your host, for example 10.0.0.1/24 so you
can access the virtual machines at 10.0.0.2 from your host with is
10.0.0.1 (in addition to its regular IP address in your network). Then
the host won't have any blocked ports at all. To let the VM have access
to the outside world, it can then also directly use the network card of
the host as bridge and does not need NAT as well - so your host will
then be visible as two machines, one is your host and the second one is
the VM inside Hyper-V.
