Describe the process of network address translation.  What are the two primary types of NAT?

What will be an ideal response?

The NAT process begins with an internal client sending a packet destined for an external host
to the NAT device. The NAT device repackages the internal client's packet and sends it to the destination host on the Internet. When the Internet host responds, the NAT device receives the packets, and then refers to a table in its memory to determine which internal client should get the packet.
There are two primary address translation types: one-to-one NAT and many-to-one NAT.
