How to assign static IP to Ubuntu Server (VirtualBox)

Question

Please see my setup here:

NAT is set up here:

Host-only adapter is enabled here:

network for virtual box is configured here:

then I set up interface on the server like this:

then I run sudo netplan apply and I should be all set. I can ping myself on the server:

but can't ping the server from my local computer:

Hence the network isn't actually connected to the Internet. What am I doing wrong here ?

update:

network connection is now set to "bridged":

Solution

The answer is Yes if you assign a static ip from your router for your virtual box virtual machine. (This need specific ip address from your local router).

The answer is No if you aren't assign a static ip from your router for your virtual box virtual machine.

If not how can we access the virtual machine via our laptop terminal ?

This is the method how to do that !

Keep in mind this is temporary method and all settings are reset after you restart the virtual machine . This will also enable internet access on your virtual box sever.

According to your question ,

First configure NAT (Network Address Translation) setting for Network Adapter 1

Then configure Host-only Adapter setting for Network Adapter 2

After that manual IP address assignment

Here don't enable the DHCP server as below

These are the settings for your server virtual machine hardware (assume that your are using a Ubuntu server virtual machine) !

After that install the Ubuntu server on the virtual hard disk ...

After you log on to the Ubuntu server (i think you provided administrative credentials ) , you have to do the followings.

First issue the following command to see the ip settings assigned for network adapters on the virtual Ubuntu server

 ubuntu@vagrant:~$ ifconfig

On my test server there are eth0 , eth1 network interface cards , I have selected eth1 for this because eth0 is already assigned with an ip address by system default.

On Ubuntu server switch to the root user as ,

 ubuntu@vagrant:~$ sudo -i

Then the appear root user prompt as below ,

 root@vagrant:~#

Then issue the following command

 root@vagrant:~# ifconfig eth1 192.168.188.101 netmask 255.255.255.0

Once you done this exit from the root user by typing exit

Here don't turn off the virtual machine !

Then minimize the virtual machine and fireup a local terminal

After that issue ifconfig on the local terminal . Here you can see the various network adapters including the host only adaptor.

Then try to ping the ip address of the virtual machine as below

user@user-laptop:~$ ping 192.168.188.101

If this ping is success you can now ssh to the your virtual Ubuntu server as below

user@user-laptop:~ ssh [email protected]

Here you can provide the virtual server password .

So I think this method is worked for you if you are interested .

You can either set the network connection to Bridged or set port forwarding on host computer.

I've set connection to "bridged" but it didn't help.

[John Ronald]

If you did so, your IP address should change and should be in the same network as hosted computer. Is that right ?

[mr_incredible]

Well ... no, because I assigned static IP of 192.168.56.102 to the server should share the name network with the host. So the IP of the server is unchanged. But I need the server to have access to the Internet from host. Bridged connection is set but didn't make difference to the virtual machine.

[mr_incredible]

I know this setup should work hence I created a thread here.

[John Ronald]

What IP does have your host PC ?

[mr_incredible]

It's 192.168.1.229. Though I'm further now. Machines can ping each other now but the server still doesn't have access to the Internet through host.
