I have a virtual machine with a static IP (I can't login to change it) with a different subnet compared to my entire network and I need to communicate with it. In particular, this is my setup:

  • Gateway (
  • Kali Linux (
  • Windows (
  • Virtual Machine (

The VM is running with Virtual Box on Windows machine while Kali is on my laptop. Both Windows and Kali are connected via ethernet to the router (

Is there a way to communicate from Kali to the VM with two different subnets?

  • Is your VM on bridged to the physical network? Does it have to access the Internet? – Daniel B Aug 18 '16 at 11:30
  • I used host-only interface, but I can't check if it has Internet connection because I don't have login credentials – Cricco95 Aug 18 '16 at 11:33
  • I’m not asking if it has Internet access (it doesn’t), but whether it wants Internet access. :D Without bridging the VM, you won’t be able to access it from other machines. – Daniel B Aug 18 '16 at 11:35
  • Ok, so I will use a bridge connection and I will retry to add the secondary IP – Cricco95 Aug 18 '16 at 11:36
  • Now I am able to ping but if I try to scan the open services with nmap there is only rpcbind while I should see a port 80 open – Cricco95 Aug 18 '16 at 11:54

You can assign your Kali laptop a secondary IP address in the 192.168.110.x range with ifconfig:

ifconfig [nic]:0 [IP-Address] netmask [mask] up

Make it permanent by modifying /etc/network/interfaces add adding an iface [nic]:0 inet static stanza which contains the address and mask you require.

  • I used this command: sudo ifconfig eth0:0 netmask up, but I can't ping the VM – Cricco95 Aug 18 '16 at 9:39

Well, if you made the firewall/router's inside interface and with a subnet mask of, it would be able to talk to both subnets without a problem.

additionally, I would probably be more a proponent of getting an additional interface for the router/firewall.
