How to work NAT and Bridged network?

Hi at all,

I'm newbie with vmware technology and I'm attempting to understand how to works in detail and precisely the NAT and Bridged network configurations but i not obtain any result.

I have made a search on the internet but i have not found any document that explain in detail the NAT and Bridged networking. There are document and page web with summary and not detailed information.

Please can any one explain me, if possible, in detail how to works? Or can any one tell me where i find a resource or document where i can learn that argument?

For example, what i want to know is the tasks of virtual network adapters VMnet0 and VMnet8.

How to WMnet0 and VMnet8 communicate with virtual network adapter and host netwrok adapter?

Thanks in advance.
