VMware three working modes (Bridged, host-only, NAT)

VMWare provides three working modes: bridged (bridging mode), NAT (network address translation mode), and host-only (host mode ). To apply them properly in network management and maintenance, you should first understand the three working modes.

L bridged (Bridging Mode)

In this mode, the Virtual Operating System of VMWare is like an independent host in the LAN, which can access any machine in the network. In the bridge mode, you need to manually configure the IP address and subnet mask for the virtual system, and also need to be in the same network segment as the host machine, so that the virtual system can communicate with the host machine. At the same time, because the virtual system is an independent host system in the LAN, You can manually configure its TCP/IP configuration information to access the Internet through the LAN gateway or router. The relationship between a virtual system in the bridge mode and the host machine is like connecting two computers on the same Hub. If you want them to communicate with each other, You need to configure the IP address and subnet mask for the virtual system. Otherwise, the communication will fail. If you want to use VMWare to create a virtual server in the LAN to provide network services for LAN users, you should select the bridge mode.

Note: The IP address, subnet mask, gateway, and dns options need to be set (no dns is set, and the IP address can be pinged, but the webpage cannot be opened. At that time, it was very depressing, and then it was OK after being set)

These settings only require two or three lines of command

L host-only (host Mode)

In some special network debugging environments, you must isolate the real environment from the virtual environment. In this case, you can adopt the host-only mode. In host-only mode, all virtual systems can communicate with each other, but the virtual system and the real network are isolated. Tip: in host-only mode, the virtual system and the host machine system can communicate with each other, equivalent to the two machines connected through twisted pair wires. In host-only mode, the TCP/IP configuration information of the virtual system (such as the IP address, gateway address, and DNS server) is created by VMnet1 (host-only) DHCP servers in the virtual network are dynamically allocated. If you want to use VMWare to create a virtual system isolated from other machines in the network and perform some special network debugging, you can select the host-only mode.

------------------------

Original part:

1. When installing the operating system on a VM, set the system IP address to 192.168.0.99 and DNS to 192.168.0.1.

2. Modify the VMnet1 ip address of the VM to 192.168.0.1.

3. Set Internet Connection Sharing on the network card that you can access the network. The specific setting method is property --> advanced --> connection sharing, and then select VMnet1 to share the network with it.

4. ping 192.168.0.99 on the local machine. If it can be pinged, it indicates that your settings are correct.

5. Go to the linux operating system on your Vm and surf the Internet.

L NAT (network address translation mode)

The NAT mode enables the virtual system to use the NAT (Network Address Translation) function to access the public network through the network of the host machine. That is to say, you can use the NAT mode to access the Internet in a virtual system. In NAT mode, the TCP/IP configuration information of the virtual system is provided by the DHCP server of the VMnet8 (NAT) Virtual Network and cannot be modified manually, therefore, the virtual system cannot communicate with other real hosts in the local area network. The biggest advantage of using the NAT mode is that it is very easy for the virtual system to access the Internet. You do not need to configure any other configurations, but only need the host machine to access the Internet. If you want to use VMWare to install a new virtual system, you can directly access the Internet without manual configuration in the virtual system. We recommend that you use the NAT mode.

Tip: The VMnet8 virtual network mentioned above in NAT mode, the VMnet1 Virtual Network in host-only mode, and the VMnet0 Virtual Network in bridged mode, they are all generated based on the automatic configuration of the vmwarevm and do not need to be set by the user. VMnet8 and VMnet1 provide DHCP services, while VMnet0 does not.
