CHAPTER 7 Networking

233

If you want to connect to the Internet or other TCP/IP network using the host

computer’s dial-up networking or broadband connection and you are not able to give

your virtual machine an IP address on the external network, NAT is often the easiest

way to give your virtual machine access to that network.

NAT also allows you to connect to a TCP/IP network using a Token Ring adapter on the

host computer.

If you use NAT, your virtual machine does not have its own IP address on the external

network. Instead, a separate private network is set up on the host computer. Your

virtual machine gets an address on that network from the VMware virtual DHCP

server. The VMware NAT device passes network data between one or more virtual

machines and the external network. It identifies incoming data packets intended for

each virtual machine and sends them to the correct destination.

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. 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.

If you make some other selection in the New Virtual Machine Wizard and later decide

you want to use NAT, you can make that change in the virtual machine settings editor

(VM > Settings). For details, see Changing the Networking Configuration on

page 238.

For a more thorough discussion of NAT, see Understanding NAT on page 269.
