Subnet 192.168.100.0/24 ping responds always when wsl-vpnkit distro is running

Hello!

First of all, thanks for the project.

I found a strange behaviour that I cannot understand yet after some problems trying to connect to a company subnet in 192.168.100.0/24 range. I realized that the subnet 192.168.100.0/24 always responds to ping when wsl-vpnkit distro, even if it seems to not exist anything in that range connected or overlapping at all.

I have modified the default.conf for wsl-vpnkit distro just in case the default 192.168.68.0/24 network was interferring somehow, but even with other private subnets applied like 172.xx.xx.xx/24 all IPs in 192.168.100.0/24 subnet responds to ping.

When I shutdown the wsl-vpnkit distro, then the 192.168.100.0/24 is not reachable, as expected.

1. Screenshot of ip a with wsl-vpnkit running:

2 )Ping to 192.168.100.0/24 IPs OK:

3. Shutdown wsl-vpnkit distro or stop service. Ping 192.168.100.0/24 IPs does not respond, as it should be.

Any idea why this is happening?
Thanks.
