Multiple NICs enable simultaneous Internet access to multiple computers (no vrouters or switches)

Multi-nic enables simultaneous Internet access to multiple computers (without routers or switches). In daily life, sometimes we want to use only one external network cable to enable simultaneous Internet access to multiple terminals. However, because vswitches or vrouters are expensive, it is often the main factor that limits us to access the Internet at the same time. The NIC is relatively cheap (the unit price is less than 10 RMB). You can simply configure it to share the network. There are many ways to do this. Here we use a desktop (dual Nic, pay attention to assigning different IP addresses to each Nic) and a notebook as an example to describe how to configure a small shared network. The desktop is used as the host. Note: The premise is that the two network cards on the desktop are correctly installed and the driver is normal. Step: first, right-click "network neighbor-properties-set home or small office network" on the host, open the "Network Installation Wizard", and click "Next" twice in a row ", open the "select connection method wizard" and select the first option "Connect this computer to the Internet ...... "; then click" Next ", select a correct connection and click Next. In the displayed dialog box, select "", click Next, enter the computer description, and click Next. Enter the workgroup name (computer name, you can enter the working group name as needed ), finally, click "Next" and click "finish this wizard. I don't need to run this wizard on another computer. The slave machine settings are basically the same as the host. in step 3, select "this computer is connected to another computer on my network ....... ", and then dial on the host to access the Internet. Note that if you want to access the Internet through the home broadband, select "allow other networks to connect to the computer" in "Broadband connection"> "properties"> "advanced" of the host ", if the campus or company VPN accesses the Internet, the host operation is the same; the slave IP is set to automatic acquisition.
