Adapter Bridge (connect to wifi or lan connected to the internet)
Host Only Adapter (To connect to Host and Guest)

# configuration ip address internet eth1 (bridge)
# dhcp
auto enp0s3
iface enp0s3 inet dhcp


# configuration eth2 atau enp0s8 (host only adapter)
# static
auto enp0s8
iface enp0s8 inet static
        address 192.168.111.1
        netmask 255.255.255.0
        network 192.168.111.0
        broadcast 192.168.111.254

To restart the ip address configuration results can use the command :

systemctl restart networking

or if you want to use other commands, you can install tools with the command : (make sure you are connected to the internet)

apt install ifupdown net-tools

If you have finished and successfully installed the tools, then friends can restart the network with another command, namely :

/etc/init.d/networking restart

Then check the configuration results using the : ifconfig

open the network and sharing center, or simply: Windows + R, then type ncpa.cpl dan enter.

Result Configuration IP address Host Only

Please do testing on the Host and Server do the ping process between devices as shown below:

ping from windows to server
