Virtual Box Bridged Adapter can't Ping Host < OR > Guest

In Virtual Box Machine Settings:

Set the WIFI as the first adapter [MTDesktop, AllowALL] Set the LAN WIRED [MTServer,AllowAll] as the second adapter.

In the Guest machine disable the First Adapter (which is bound to the wifi) in Adapter Settings.

Set your IP Address on the Guests Second Adapter. You can then ping internal, external whatever - using my guests second adapter.

One other issue can cause this: If you Locally Administer the MAC address in the Guest Image rather than via the VirtualBox settings you will also have the same issue of not being able to communicate with host (vice versa) or outside devices.

Virtual Box 5.2.22 other versions are probably affected.
