I have set local ubuntu 16.04 server yesterday. I configurated static IP and everything was good. I was able to connect to the server. Today I travelled to city, where i stydy. The server couldnt work becouse of diffrent router settings.

For the last few hours im trying to make it work again. My base system is Windows 10, then I have linux mint 17.3 on virtual machine. On linux i have ubuntu server. In both cases im using virtualbox to host VM's.

Output of ipconfig in Windows:

IPv4 Address 192.168.1.10
Subnet Mask 255.255.255.0
Default Gateway 192.168.1.1

I have two network adapters connected to ubuntu: Host-only and NAT.Host-only settings

Configuration of /etc/network/interfaces

auto lo
iface lo inet loopback
auto enp0s3
address 192.168.1.20
netmask 255.255.255.0
network 192.168.1.1
broadcast 192.168.1.255
auto enp0s8
iface enp0s8 inet dhcp

Ifconfig for enp0s3 show me:

inet addr: 192.168.1.20

Ubuntu server has internet connection(i can ping google.com) but i cant connect to local server. Would appreciate any kind of help.

I'd suggest changing the NAT adapter to a network bridge adapter. NAT means it is essentially using the IP of your host, which in this case is 192.168.1.10. From there, Virtualbox will act as a router.

Setting it to network bridge adapter will connect the virtual machine to your "real" network.

  • Thanks for quick anserw. Changing the second adapter to bridge or even disabling it doesnt make any diffrence. Can you advise me how should i configure my windows network adapter(ones that uses linux mint)? Atm i configured them as nat and host-only – Szymon Strzelka May 23 '16 at 16:36
  • I'm not entirely sure how your virtual machines are setup. Are you saying that you are two different physical machines? One with a Mint VM and one with an Ubuntu Server VM? – Bram Koert May 23 '16 at 17:26
  • I have one physical machine. Windows hosts linux, linux hosts ubuntu – Szymon Strzelka May 23 '16 at 17:27
  • Why are you using a VM inside of a VM? – Bram Koert May 23 '16 at 17:28
  • Because i set mint for my my colleague projects. Then i was force to set another machine to cooperete with mint – Szymon Strzelka May 23 '16 at 17:29
