Example of a Custom Networking Configuration

With the Workstation virtual networking components, you can create sophisticated virtual networks. The virtual networks can be connected to one or more external networks, or they can run entirely on the host computer. On Windows hosts, you can use the virtual network editor to access multiple network cards in your host and create multiple virtual networks.

Before you attempt to set up complex virtual networks, you need a good understanding of how to configure network devices in your host and guest operating systems. Figure below shows most of the ways you can combine devices on a virtual network. In this example, a Web server connects through a firewall to an external network. An administrator’s computer connects to the Web server through a second firewall.

VMware Workstation: Host-Only Networking

Host-Only Networking

Host‐only networking creates a network that is completely contained within the host computer. Host‐only networking provides a network connection between the virtual machine and the host computer, using a virtual network adapter that is visible to the host operating system. This approach can be useful if you need to set up an isolated virtual network. In this configuration, the virtual machine cannot connect to the Internet.

VMware Workstation: Network Address Translation (NAT)

Network Address Translation (NAT)

NAT configures a virtual machine to share the IP and MAC addresses of the host. The virtual machine and the host share a single network identity that is not visible outside the network. NAT can be useful when your network administrator lets you use a single IP address or MAC address. If cannot give your virtual machine an IP address on the external network, you can use NAT to give your virtual machine access to the Internet or another TCP/IP network. NAT uses the host computer’s network connection. NAT works with Ethernet, DSL, and phone modems.

NAT Setup

If you select NAT, the virtual machine can use many standard TCP/IP protocols to connect to other machines on the external network. For example, you can use HTTP to browse Web sites, FTP to transfer files, and Telnet to log on to other computers. NAT also lets you to connect to a TCP/IP network by using a Token Ring adapter on the host computer.

In the default configuration, computers on the external network cannot initiate connections to the virtual machine. That means, for example, that the default configuration does not let you use the virtual machine as a Web server to send Web pages to computers on the external network. This configuration protects the guest operating system from being compromised before you have a chance to install security software.

VMware Workstation: Bridged Networking

Bridged Networking

Bridged networking connects a virtual machine to a network by using the host computer’s network adapter. If your host computer is on a network, this is often the easiest way to give your virtual machine access to that network. The virtual network adapter in the virtual machine connects to the physical network adapter in your host computer, allowing it to connect to the LAN the host computer uses.

Bridged networking configures your virtual machine as a unique identity on the network, separate from and unrelated to its host. It makes the virtual machine visible to other computers on the network, and they can communicate directly with the virtual machine. Bridged networking works with both wired and wireless physical host network cards.

VMware Workstation: Common Networking Configurations

( Please try to translate this post in a natural way from English to Spanish )

When you choose the standard networking options in the New Virtual Machine wizard or the virtual machine settings editor, the networking configurations are set up for you automatically.

If you select the Typical setup path in the New Virtual Machine wizard, the wizard sets up network address translation (NAT) for the virtual machine. Select the Custom setup path to choose any of the common configurations: bridged networking, NAT, or host‐only networking. The wizard connects the virtual machine to the appropriate virtual network.

You can set up more specialized configurations by choosing the appropriate settings in the virtual machine settings editor, in the virtual network editor (on Windows and Linux hosts), and on your host computer. On all hosts, the software needed for all networking configurations is installed when you install Workstation.

You can connect multiple virtual machines to the same virtual Ethernet switch. On a Windows host, you can connect an unlimited number of virtual network devices to a virtual switch. On a Linux host, you can connect up to 32 devices.

If you have set your virtual network settings on a previous version of Workstation and upgrade to a new version, your previous network settings might be fully or partially preserved.

VMware Workstation: Components of the Virtual Network

Workstation provides the bridged, network address translation (NAT), host‐only networking, and custom networking options to configure a virtual machine for virtual networking.

Virtual Switch

Like a physical switch, a virtual switch lets you connect other networking components together. Virtual switches are created as needed by Workstation, up to a total of 10 virtual switches on Windows and 255 on Linux. You can connect one or more virtual machines to a switch. By default, a few of the virtual switches are mapped to specific networks.

Default Virtual Network Switches
=======================
Network Type     Switch Name
=======================
Bridged                   VMnet0
—————————-
NAT                        VMnet8
—————————-
Host‐only               VMnet1
—————————-

The other available networks are named VMnet2, VMnet3, VMnet4, and so on.

DHCP Server

The dynamic host configuration protocol (DHCP) server provides IP network addresses to virtual machines in configurations that are not bridged to an external network. For example, host‐only and NAT configurations use the DHCP server

Network Adapter

A virtual network adapter is set up for your virtual machine when you use any type of networking to create it with the New Virtual Machine wizard. It appears in the guest operating system as an AMD PCNET PCI adapter or as an Intel Pro/1000 MT Server Adapter. On Windows Vista and Windows 7 guests, it is an Intel Pro/1000 MT Server Adapter.

Use the virtual machine settings editor to create and configure up to 10 network adapters in each Workstation 6.0 and higher virtual machine. The limit is three adapters for Workstation 4 or 5.x virtual machines.
