The virtual machine’s network traffic appears as if it originates from the host machine, effectively hiding the virtual machine’s IP address from the outside world. NAT mode is ideal for basic internet access and for scenarios where the virtual machine needs to be isolated from the host network.
Bridged: Bridged mode allows the virtual machine to act as a separate device on the host’s network. The virtual machine obtains an IP address directly from the host’s network using DHCP (Dynamic Host Configuration Protocol). In this mode, the virtual machine is seen as a separate device on the network, and it can communicate directly with other devices on the same network. This mode is suitable for scenarios where the virtual machine needs to be accessible from other devices on the network, such as servers or network-connected devices.
Host-only: Host-only mode creates a separate, isolated network for the virtual machine and the host machine. This mode uses a virtual network interface card (NIC) that is only accessible to the virtual machine and the host machine. The virtual machine obtains an IP address from the host-only network, which is not accessible from the outside world. This mode is ideal for scenarios where the virtual machine needs to be isolated from the internet and other devices on the host’s network, such as for testing or development purposes.

Configuring Network Settings

To configure network settings for virtual machines, follow these steps:

Open the virtual machine settings: Right-click on the virtual machine in the VMware Workstation interface and select “Settings.”
Select the “Network Adapter” option: In the virtual machine settings, navigate to the “Network Adapter” section.
Choose the desired network mode: Select the desired network mode from the dropdown menu under “Connect network adapter to:”

Apply the changes: Click “OK” to save the changes and close the settings window.

Examples of Network Connectivity

Scenario 1: Basic internet access: For basic internet access, NAT mode is the most suitable option. This mode allows the virtual machine to access the internet using the host’s network connection. The virtual machine’s traffic is routed through the host, and the host’s IP address is used to access the internet. This mode is ideal for general browsing, email, and other internet-based activities.
Scenario 2: Accessing a network server: For accessing a network server, bridged mode is the most suitable option. This mode allows the virtual machine to act as a separate device on the host’s network. The virtual machine obtains an IP address directly from the host’s network, enabling communication with other devices on the same network. This mode is ideal for accessing shared resources, such as network printers, files, or other servers.
Scenario 3: Testing a web application: For testing a web application, host-only mode is the most suitable option. This mode creates a separate, isolated network for the virtual machine and the host machine. The virtual machine can access the web application running on the host machine, while remaining isolated from the internet and other devices on the host’s network. This mode is ideal for testing and development purposes, where the application needs to be tested in a controlled environment.
