script that set up few nats at once

Hello,

im tired to set up nats with vmware "virtual network editor" tool. I want to write windows script that

will do it for me. I found information about C:\ProgramData\VMware\vmnetnat.conf file in workstation 9.0

manual. But editing it dosnt work for me, meybe becouse i use Windows 8 or becouse it dosnt work

at all. I noticed that this file dosnt contain description for nats so it seems that it is wrong place to

edit nats. Any ideas where can i write nats or which tool i have to use to do it automatically?
