Editing the NAT Configuration File
If you are an advanced user, you can edit the NAT configuration file to modify NAT settings.
The location of the NAT configuration file depends on the host operating system.
Table 5-3. NAT Configuration File Location
Host Operating System NAT Configuration File Location
Windows XP C:\Documents and Settings\All Users\Application
Data\VMware\vmnetnat.conf
Windows Vista or Windows 7
C:\ProgramData\VMware\vmnetnat.conf
Linux /etc/vmware/vmnet8/nat/nat.conf
The NAT configuration file is divided into sections, and each section configures a part of the NAT device. Text
surrounded by square brackets, such as
[dns]
, marks the beginning of a section. Each section contains one or
more configuration parameters. The configuration parameters take the form
ip = 192.168.27.1/24
.
On a Windows host system, you can change the NAT configuration by using the virtual network editor. You
do not need to edit the NAT configuration file. On a Linux host system, you must edit the NAT configuration
file to modify the NAT configuration.

Make a backup copy of the NAT configuration file. If you edit the NAT configuration file and then
use the virtual network editor, your edits might be lost.
NAT Configuration File Sections
The NAT configuration file is divided into sections. The parameters in each section configure a part of the NAT
device.
[host] Section
The [host] section includes parameters to configure the NAT connection.
Table 5-4. [host] Section Parameters
Parameter Description
ip
The IP address that the NAT device should use. It can be followed by a slash and the
number of bits in the subnet.
netmask The subnet mask to use for the NAT network. DHCP addresses are allocated from this
range of addresses.
configport A port that can be used to access status information about the NAT device.
device
The VMnet device to use. Windows devices are of the form vmnet x where x is the
number of the VMnet. Linux devices are of the form /dev/vmnet x .
activeFTP
Flag to indicate if active FTP is to be allowed. Active FTP allows incoming connections
to be opened by the remote FTP server. Turning this off means that only passive mode
FTP works. Set this flag to 0 to turn it off.
[udp] Section
The [udp] section contains the
timeout
parameter, which specifies the number of seconds to keep the UDP
mapping for the NAT network.
[dns] Section
The [dns] section is for Windows hosts only. Linux hosts do not use this section.
