Understanding VMware Workstation Network Modes: Bridge, NAT, and Host‑Only Explained

When configuring a virtual machine in VMware Workstation, three network modes are available: Bridge, NAT, and Host‑Only. This guide explains each mode, the associated virtual adapters (VMnet0, VMnet1, VMnet8), and how to set them up.

Bridge Mode

The Bridge mode connects the VM directly to the external network via the physical NIC. In the Virtual Network Editor (Edit → Virtual Network Editor → Change Settings) you can select the physical NIC to bridge (e.g., the wireless adapter). The VMnet0 virtual switch bridges to the physical NIC, sharing the host’s network and receiving an IP address from the same DHCP server as the host.

VMnet0 is primarily used for host‑only networking; when bridged, it allows the VM to access external networks just like the host.

VMnet0 has limited use; it creates a virtual bridge for the host but cannot reach external networks unless bridged.

When Bridge mode is selected, the "Copy physical network connection state" option lets the VM detect changes in the host’s network (e.g., switching from wired to wireless) and reconnect automatically.

If the host cannot ping the VM (or vice‑versa), the default firewall may be blocking ICMP; disabling the firewall restores ping connectivity.

NAT Mode

NAT mode shares the host’s IP address. The VMnet8 virtual NIC connects to the VMnet8 virtual switch, which runs a DHCP server assigning addresses in the 192.168.5.0/24 range. A NAT device then translates this private network to the host’s external IP (gateway 192.168.5.2).

Compared with Bridge mode, NAT isolates the virtual network from the host’s network, improving security and conserving IP addresses, but requires NAT mapping for external access, making configuration more complex.

Host‑Only Mode

Host‑Only creates a private network (VMnet1) that connects the VM to the host without external access. The VMnet1 virtual switch links the VM and host, allowing communication only within this isolated LAN.

The topology is simpler than NAT because the NAT device is omitted. DHCP can be configured or disabled for static IP assignment, but all interfaces must be on the same subnet to communicate.
