VMWare question

Is it possible to run a second server on a virtual machine using VMWare, in NAT network? Or it requires bridged network with 2 IP address?

I think yes . because Silkroad online with the same ip for every servers you can connect to ... else you must connect with the general connection ( 27/28/29/30 )
