You can also add Port Forwarding for accessing VM (over ssh or http kind of protocols). Open VirtualBox Preferences ( File -> Preferences) and go to Network Tab. Create a NAT Network using VirtualBox GUI

Also these VM’s was talk to outside world (Virtual host, local network and internet) How to Create a NAT Network Image Courtesy: You can create NAT Network from the VirtualBox GUI or by using VBoxManageutility. All the VM’s connected to the NAT Network can talk each other as in the same network. This is not really needed if you can configure and use a NAT Network. Image Courtesy: So I found people create internal network interface for the VM’s and assign a different IP address to talk each other.

But the with NAT interface will not be able to talk to another VM with NAT interface and not suitable for your case. Eg: I want to do Penetration Testing on some VM’s and I do not want to interrupt other network on host or in the environment.īy default the VirtualBox will create a network interface for VM with NAT mode by which you can access the outside world (including internet) from the VM. But you do not want other machines in the VirtualBox or Virtual Host (your laptop or workstation) or other devices in the network to talk to these VM. Here is the scenario: You are doing some labs with multiple Virtual Machines and you need those VM’s to talk each other. Scenario : Create VM’s in Isolated Network There is no harm on that but you can achieve the same result using NAT Network in VirtualBox. Recently I noticed that, some of the engineers are creating labs in VirtualBox but they are adding more and more interface for multiple type of connections. When we talk about local development or PoC (Proof of Concept) environments, VirtualBox is my first choice as it gives me the choice of multiple options in terms of networking and other features. Open Putty, and in the 'Host Name (or IP address)' field, enter: '127.0.0.Photo by Brett Sayles from Pexels Introduction.You need to remember the username you created on your Guest! Remember, you CANNOT log in as root using SSH, so this will have to be the user you created.

For Linux and Mac users, use the built in terminal. To do so, use the Putty terminal emulator (if you are on Windows). Now, it's time to try and connect to the Guest. This means that your Host is listening on port 2222 for connections. Use the space bar to move one page at a time, and look for a line similar to this: tcp4 0 0 0.0.

You will probably need to restart the Virtual Machine so that the changes are applied: Click OK again to exit the Network Settings. You are back in the Network Settings windows. "If a TCP connection is received on the Host on TCP port 2222, send it on to the Guest on TCP port 22" Guest IP is left blank - there is no need by default to change this.It means that ANY MACHINE that can access your Host on TCP port 2222 will be able to talk to the SSH on your guest.
