Mastering VMware Workstation: Configure Bridged, Host‑Only, and NAT Networking

Introduction

VMware Workstation (VM) is a powerful virtualization tool that allows multiple operating systems to run simultaneously on a single desktop, simulating complete network environments with features such as PXE, snapshots, and resource savings for testing and deployment.

The article focuses on VM's three network connection modes and does not cover virtual CPU, memory, or other hardware settings.

Virtual Network Devices

In real life, machines connect via physical NICs, switches, routers, and cables. VM simulates these devices in software.

VM creates the following virtual devices:

Host physical and virtual NICs (e.g., vmnet1 and vmnet8 virtual NICs, plus the host's real NIC).

Guest virtual NICs (shown in the second image).

Virtual switches (VMnet0‑9).

DHCP and NAT Services

VM provides DHCP services on vmnet1 (host‑only) and vmnet8 (NAT) networks, assigning IP addresses, subnet masks, and other parameters to guest VMs. The DHCP configuration can be viewed in the service manager (run services.msc).

For Internet access, VM uses a NAT service that translates guest IPs to the host's external IP.

Three Network Modes Explained

Bridged mode : The guest NIC connects to the host's physical NIC via a virtual bridge, appearing as a separate machine on the physical network and receiving an IP from the external DHCP server.

Host‑only mode : Guest NIC connects only to vmnet1 virtual switch; the host and guests can communicate, but there is no Internet access because no router is present.

NAT mode : Guest NIC connects to vmnet8 virtual switch; the host provides NAT translation, allowing guests to reach the Internet while remaining on a private subnet.

Summary

VMware Workstation solves networking challenges by simulating NICs, virtual switches, DHCP, and NAT services. To enable guest‑to‑external communication, DHCP and NAT services plus a virtual switch are required. The article sets the stage for deeper exploration of each mode.
