When installing plugin with vnet setting, at first, I can't choose interface and ip address. I have to tick the NAT and remove the tick again, and like this, the settings will be available, but the installation ends with an error and the plugin isn't installed.
When I set NAT through the special settings, the plugin installation ends with an error again (natnotwork) and the plugin isn't installed as well.
The plugin installation works with NAT without any special possibilities, in addition, it always works with DHCP.
I'm attaching screenshots of the bugs.
