Virtual Box guest on different subnet than host

Question

I currently have my Debian VM using NAT and it is on subnet 10.0.2.x where my host is on 192.168.0.x how can I get my guest on the same subnet as my host?

Host:

Ethernet adapter VirtualBox Host-Only Network #2:

   Connection-specific DNS Suffix  . : 
   Link-local IPv6 Address . . . . . : fe80::b0cd:11de:7c85:f11a%16
   IPv4 Address. . . . . . . . . . . : 192.168.56.1
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 

Ethernet adapter Ethernet 2:

   Media State . . . . . . . . . . . : Media disconnected
   Connection-specific DNS Suffix  . : 

Wireless LAN adapter Wi-Fi:

Can you please post the output of `ifconfig` from your host and vm machines? — ARG, Nov 13 '15 at 22:37
Did you set the guest networking settings to be in bridged mode? — ARG, Nov 13 '15 at 22:51
No, I would like to make it on NAT or Host only if possible. — Nitro, Nov 13 '15 at 22:53
Then I think you might be better off assigning static IPs. I have personally never done that before, but you can read up about it here https://www.vmware.com/support/ws5/doc/ws_net_advanced_ipaddress.html — ARG, Nov 13 '15 at 22:58
No, really, if you want NAT rather than bridged mode then the VM should be on a different IP subnet. If you want the VM on the same IP subnet as the host, you should use bridged mode. — cas, Nov 13 '15 at 23:10

What you describe is the result of having the virtual machine's network adapter in "NAT" mode; in this mode your host machine is acting as a router for your VM.

If you want your VM to be on the same IP subnet as the host machine, the interface must be set in "bridged" mode; this allows network traffic to go seamlessly between the VM and other devices on the physical network.
