VMware GSX Server Virtual Machine Guide
NAT device — The NAT (network address translation) device allows you to connect
your virtual machines to an external network when you have only one IP network
address on the physical network, and that address is used by the host computer. You
can, for example, use NAT to connect your virtual machines to the Internet through a
dial-up connection on the host computer or through the host computer’s Ethernet
adapter or wireless Ethernet adapter. NAT is also useful when you need to connect to
a non-Ethernet network, such as Token Ring or ATM.
The NAT device is set up automatically when you install GSX Server. (On a Linux host,
you must choose to make NAT available to your virtual machines.)
DHCP server — The DHCP (dynamic host configuration protocol) 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.
Network adapter — One virtual network adapter is set up for your virtual machine
when you create it with the New Virtual Machine Wizard using any type of networking
(a virtual network adapter is always added to a virtual machine created with the
VMware Management Interface). It appears to the guest operating system as an AMD
PCNET PCI adapter.
You can create and configure up to four virtual network adapters in each virtual
machine using the virtual machine settings editor.
The adapter can use one of two drivers. You can choose between the vlance driver,
which installs automatically, and the vmxnet driver, which provides better network
performance. The difference in network performance is most noticeable if the virtual
machine is connected to a Gigabit Ethernet card on the host.
