Hello,
I have noticed that there is no route from a VM to the host machine when using a bridged network interface.
In my case I'm using homeassistant on a VM, but I have also tried Mint and the same issue is present.
The VMs see all other devices on the network, so the network bridge works fine, but it's impossible to contact the host machine.
Using the NAT option for the network adapter results in no connectivity at all. I assume that is because there is no option for setting the route table.
I think this is a critical issue, considering that in many cases it's required.
