How do I connect a virtual machine to a physical host in bridge mode?

Knowledge of VMware virtual networking.

1.Virtual bridges.

Connect the virtual NIC of the virtual machine to the physical NIC of the host through a virtual bridge. It allows you to connect a virtual machine to the external network where the host is located. If there is more than one physical NIC on the host, use custom configuration to create another virtual bridge to connect to other physical NIC on the host.

2.Host virtual network interface.

After installing the virtual machine, we right-click on the "Network Neighbor" property In the "Network Connections" window that opens, we see two network cards, by default, "VMware Network Adapter VMNet1" is used only by the host network; The VMware Network Adapter VMNet8 is used by NAT networks. Right-click the properties of these two NICs, and we can see the full names of virtual NICs under the Common Label. Of course, we can also enter ipconfig in the "command prompt" of the host to get the details of the host virtual network NIC.

Device NAT is an abbreviation for Network Address Translation. When the host only has one IP outside, the virtual machine can connect to the external network using the NAT device, we open the "Service" in the "Management Tools" on the host, and we can find that there is an additional "VMware NAT Service" service, which means that the system has installed it as a system service.

DHCP services.

DHCP is an abbreviation for Dynamic Host Configuration Protocol. The DHCP service provides IP addresses for virtual machines that are not bridged to an external network. The IP address of the virtual machine in the bridged network mode is provided directly by the DHCP server on the external network where the host is located.

My answer to this question is the most correct, when you build a web host, set the network connection to NAT, don't change it after it is built. Bridges don't work, and neither does host-only. Just NAT

You can modify the IP address of the virtual machine so that it is on the same network segment as the physical host.

The physical host has one NIC and then creates a virtual NIC.

The physical NIC of the physical host is used to access the Internet, and the virtual NIC is set to be in the same segment as the IP of the virtual machine!

That's pretty much it!

How to set up the network connection (NAT mode and bridge mode) on the CentOS system installed on the virtual machine

If VMware is used in Linux, if the host is using a wireless network card, the client network card cannot be connected if the bridge is used.

According to the results of the discussion on the VMware forum, if the host is Windows, there is no problem, and the driver supports the wireless network card to work as AP mode, which is 99% not possible under Linux. It can be solved with practice and requires two steps:

2. The client's NIC configuration does not select bridge, but prompts which device to bridge the wireless NIC to when VMware runs the config, and selects Custom accordingly (Note: It is not to select the bridged bridge mode, otherwise it is impossible to connect.) This is a mistake that I have made in the past with everyone else. , and then select the corresponding device from the drop-down list, for example, vmnet2 is bridged to wlan0 on my machine, so vmnet2 is selected;

The settings are as follows:-> Virtual Networker;

2.Set the network connection mode as: Bridge (Automatic);

Before turning on the virtual machine. Then set up PPPOE dial-up in the virtual machine, that is, you can use the virtual NIC as a real NIC and click "bridged: directly connect to the physical network" in the support option on the right; (Bridge mode:.)

How to set up the network connection (NAT mode and bridge mode) on the CentOS system installed on the virtual machine

There are 4 ways to access the Internet in VMware virtual machines, and today I will talk about the first two. They are bridging mode and NAT mode.

1. Bridging mode.

1. In this mode, the virtual machine directly uses the host's network card to access the Internet, so it is relatively simple.

2. The virtual machine and the host use the same public network IP address, and the external network device cannot directly access it.

3. The virtual machine and the host have different private IPs, and the virtual machine can communicate with the host.

4. Other hosts in the LAN can also communicate with the virtual machine, for example, the mobile phone can communicate with the virtual machine by connecting to wifi.

2. NAT mode.

1. In this case, the virtual machine uses the virtual network interface vmware network adapter 8 to access the Internet.

How to set up a LAN between a VMware virtual machine and a host:

1. After installing the virtual machine VMware, you can see two more virtual network cards in the network connection, VMware Network Adapter VMNet1 and VMware

network adapter vmnet8。

2. Set up the network, use the wireless network (if it is a local connection, the setting method is the same), right-click to select the wireless network connection, select Advanced in the properties window, check Allow other network users to connect through the Internet connection of this computer, and in the home network connection, select VMware

network adapter vmnet8, OK.

3. Check the network connection properties of VMware Network Adapter VMNet8, which is automatically set to ,.

4. Start the virtual machine, enter the virtual machine operating system, set the network connection of the virtual machine, set the IP to, the subnet mask to, and the gateway to the gateway to VMware

network adapter

VMNet8 virtual network card IP address), DNS is set to the DNS of the host network connection, (the DNS of the connection to the external network, using the wireless network connection, so find the DNS of the wireless network connection, if it is a broadband connection, it is the DNS of the local connection).

First of all, my console's wired connection is normal, as follows:

However, the network connection mode of my virtual machine is bridge mode, but it cannot connect to the network, as follows:

Let's confirm the network mode of my virtual machine as follows:

The settings are all correct, but why can't I get online?

Later I found out that there was a problem with the settings of the virtual network, as follows:

We click on "Virtual Networker" as follows:

From the above figure, we can know that my "Bridge to" setting is wrong, I have set it to a wireless network card.

Let's modify it to a wired network card, as follows:

Once the changes are complete, we can connect to the Internet:

Installed VMtools?

The gateway is set to the same.

It was easy to set up when I played with ubuntu.

You must have 2 broadband connections.
