Configuring Virtual Machine 157

Shared Networking (NAT)

By default, virtual machines created during Express or Typical OS installation use Shared

Networking (NAT) mode for network connections. In this mode your virtual machine can

access the Internet while being invisible to other computers on the network (except your

Macintosh computer). This mode is recommended because it doesn't require any additional

configuring. Your virtual machine will share whatever network connection your computer uses

at the moment.

This mode is preferred in the following cases:

 your computer accesses the Internet via a modem or another non-Ethernet device,

 as a mobile user, you access the Internet from Internet cafes, hotel rooms and on flights,

 you want to access the Internet in a virtual machine but you are concerned about security,

 you have problems with Bridged Ethernet mode.

Parallels NAT adapter installed along with Parallels Desktop provides Shared networking support

in Mac OS X. IP addresses for the virtual machines are provided by Parallels DHCP server

connected to the Parallels NAT adapter.

Configuring Shared Networking for a Virtual Machine

Open Configuration Editor for the virtual machine and on the Network Adapter Options (page

182) tab select the Shared networking option.

If you want your virtual machine to have an IP address from the specific range, then:

 Choose Preferences from Parallels Desktop menu. On the Network (page 220) tab, specify a

range of IP addresses to be assigned to the virtual machines and your primary OS in the

Enable DHCP Scope for Shared Networking group.

 Note that this scope of addresses must be different from the scopes of all other networks

your Macintosh computer has access to.

Bridged Ethernet Networking

If your virtual machine uses the Bridged Ethernet type of connection to the network, virtual

machine appears on the network as a stand-alone computer with its own IP address and network

name.

To configure your virtual machine to use Bridged Ethernet mode:

1 Open Configuration Editor for the virtual machine and on the Network Adapter Options

(page 182) tab select the Bridged Ethernet mode in the Emulation group

2 Choose the proper network adapter from the list. The Default Adapter option is

recommended. It connects to the built-in Ethernet or AirPort of your Macintosh computer

whichever is currently active.

3 Configure network options in the guest operating system.
