Bridged Network from Windows 10 host to Ubuntu 18.04 guest in Virtualbox not working

Question

I've been a Windows poweruser since forever and lately I got more interested in hosting and webservers. That's when the time has come to get my hands dirty with Linux and so I decided today to create a virtual machine running Ubuntu 18.04, installing apache on it and doing my first baby steps.

Unfortunately, I can only reach the webserver on Ubuntu, not on the host machine or any other device connected to the internet. Some googling later, I found out that I have to switch network adapter to bridged.

Now comes my issue. After i switched to bridged, the network connection is gone - and i tried to find a solution during the last 5h, by changing some stuff here and there or reinstalling the OS - without luck.

Since I'm a fresh born baby with this OS, I wanted to hear from some Linux poweruser what the issue could be and how I could solve it?

Error: Activation of Network connection failed

ifconfig with bridged Network:

Virtual box Network settings:

/etc/network/interface file

Answer 1

I have a clue for you: Changing the network type on the VirtualBox side does not change how the VM "sees" it's network. The VM has the same virtual network interface, so the problem is on the host/network, not in the VM.

If you feel more comfortable with windows, try to install a windows VM with the bridged network, this will probably show you that the problem is on the host/network side.

• Verify your firewall let the VM send and receive packets to the outside
• Try a wired connection (if possible), your access point is perhaps refusing to give an IP address to your VM.
• The last ressort will be to use NAT+Port forwarding.

Answer 2

Try this: put NAT mode, then do port-forwarding by forwarding the ports to the host's card. Of course you must have the address of the virtual machine and the host machine.
