virtualbox.org

I have a PC that is not connected to a network, on this system I am running a virtualbox VM. I have a shared folder on the host PC, I am unable to connect to it at all from the virtualbox VM.

The host machine has a 'VirtualBox Host-Only Network Adapter' and the VM has a NAT adapter

Host
IP : 192.168.0.100
Subnet : 255.255.255.0
Default Gateway : Blank
Preferred DNS Server : Blank
Alternate DNS Server : Blank

VM
IP : 192.168.0.99
Subnet : 255.255.255.0
Default Gateway : Blank
Preferred DNS Server : Blank
Alternate DNS Server : Blank
What should I out for the gateway and DNS for both?

The guest would also need to be using the host-only adapter for proper communications.
