VirtualBox Network Settings: NAT vs Bridged Modes Explained

VirtualBox provides users with a range of networking options to ensure seamless communication between virtual machines (VMs) and the host machine. Two of the most commonly used modes are NAT (Network Address Translation) and bridged networking. In this article, we will delve into the differences between these two modes, exploring their advantages and disadvantages, and provide step-by-step instructions on how to configure bridged networking in VirtualBox.

Understanding Bridged Networking Mode

In bridged networking mode, a device driver called 'net filter' is used on the host machine. This allows the VM to be assigned an IP address from the same network as the host machine, making it appear as if the VM is directly connected to the network. To overcome the limitations of this mode, VirtualBox introduced bridged networking.

Limitations of Bridged Networking Mode

One major drawback of bridged networking mode is that other devices, including the host machine and VMs on the network, cannot access the guest VM or the outside internet. The host can only access selected services on the VM using port forwarding.

Default NAT (Network Address Translation) Mode in VirtualBox

NAT is the default networking mode for any new VM inside VirtualBox. This mode allows the VM to share the host's internet connection and communicate with other devices on the network, while keeping its own IP address private.

Key Differences Between Bridged and NAT Modes

Here are some key differences between bridged and NAT modes in VirtualBox:

* In bridged mode, the VM is assigned an IP address from the same network as the host machine.

* In NAT mode, the VM is assigned a private IP address by VirtualBox.

* Bridged mode allows other devices on the network to access the guest VM, while NAT mode does not.

Configuring Bridged Networking Mode in VirtualBox

To configure bridged networking mode in VirtualBox, follow these steps:

1. Launch Oracle VirtualBox and select the VM you want to configure.

2. Click on Settings and then select Network.

3. In the Network settings window, select 'Bridged Adapter' as the network interface.

4. Select the desired network interface from the drop-down menu.

VirtualBox provides users with a range of networking options to meet their specific needs. By understanding the differences between NAT and bridged modes, you can choose the mode that best suits your requirements. Whether you need to share files or access services on the host machine, VirtualBox has got you covered.
