Cannot ping VboxNet0 or any guest machine

[FernandoEwald]

I have a MAC runniung MACos 10.13.6
Virtual box Version 5.2.18 r124319 (Qt5.6.3)

I cannot ping my MacOS vboxnet0 from my mac
I cannot ping any other guest machine from my mac
from the guest machine I can ping any other guest but cannot ping the MACOS
is there any solution?

My MacOS IP:

vboxnet0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
	ether 0a:00:27:00:00:00 
	inet 192.168.56.1 netmask 0xffffff00 broadcast 192.168.56.25

My linux guest:

enp0s8: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.56.18  netmask 255.255.255.0  broadcast 192.168.56.255

From the host, post the output of:

• VBoxManage list hostonlyifs
  ping <guest>    <--- substitute <guest> with the actual IP

I'd like to see a VM log from a complete VM run:

• Start the VM from cold-boot (not from a paused or saved state) / Observe error / Shutdown the VM (force close it if you have to).
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response (see the "Upload attachment" tab below the reply form).
