Virtualbox over windows-10, how to run "Virtual Host Adapter"?

Question

virtual box

There is Windows 10 Home, Virtualbox in it, Ubuntu inside it.
Ubuntu has a network adapter configured as a "virtual host adapter" and attached to the "virtualbox host-only network adapter #4" interface (the second adapter is nat, there are no problems with it).
In ubuntu-guest the address is configured 192.168.99.100/24, in host-windows 192.168.99.1/24:

C:\Users\pavel>ipconfig /renew

Meanwhile, Windows sends pings to 192.168.99.100 not to the virtual adapter, but to the default gateway.

C:\Users\pavel>tracert -d 192.168.99.100

What to do?

Answer 1

You need to figure it out in order, in ubuntu you set the dynamics and output it to the local network (see the virtualbox settings) and ping the LAN gateway if everything is ok, then the problem is in the ubunta roof settings, if not, then in the hot machine + VM
