Using NAT with Vsphere Web Client

I have a question about using NAT on VMs in Vsphere Web Client. In Vmware workstation I know that you simply click edit > virtual network editor, and then select "NAT" configure the subnet IP and then the netmask and then simply click on the network adapter and chose the specified virtual network to have DHCP give you an IP in the range you specified.

I simply can not figure out how to use this same sort of configuration on Vsphere 5 web client.

Thanks
