I have written several times about this particular topic here.

Yes, the behavior changed. Previously if you try to ping 10.0.0.1 the
packets leak onto the wire even though that's a local address. And you
cannot connect to the local end, again, packets go on the wire towards
possibly the default gateway.

I will take a look and let you know what the issue might be.
