Ask experts to point out the problem about vmware establishing virtual network.

Vmware is just a virtual machine tool, which should meet your needs. If you want to simulate a small LAN, you'd better install a network operating system, such as 2003 or linux, depending on what you want to learn and experiment. Of course, you should also install several other types of operating systems, such as 98,2000 Pro, xp and so on. To simulate a more realistic network environment and test more complex network problems.

You can learn a lot by installing several servers in 2000 or 2003, and then upgrading one or more of them to dc, installing exchange, isa server and so on.

If the virtual machine you are talking about is VMware.

As long as the network application is not very complicated, I can tell you.

Congratulations, you don't need to buy a network card at all.

Usually, we use two virtual machine networks.

One is a bridge.

One is Nate.

Let me briefly talk about the difference between the two.

Bridges are mainly used in networks with switches or routers without IP restrictions (that is, the network where your real machine is located is a relatively free LAN)

NAT is mainly used in router LAN with limited IP address (that is, the network where your real machine is located is a LAN that can only access the Internet with a single IP).

A little more professional is that the bridge is a layer 2 device and NAT is a layer 3 device.
