NAT, is use to save IP addresses. In a nut shell.
On your LAN you would use private IP addresses, you map these to a public address and that would router through the ether.

remember these commands :
ip nat pool zzzz xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy NETMASK mmm.mmm.mmm.mmm
ip nat pool zzzz xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy PREFIX-LENGTH pp
zzz is the name of the pool
xxx.xxx.xxx.xxx is the first address of the pool
yyy.yyy.yyy.yyy is the last address of the pool
mmm.mmm.mmm.mmm the mask used to define this pool
pp is the prefix use for CIDR mask definition (ex: 25 for 255.255.255.128)
NETMASK or PREFIX-LENGTH are compulsory so better not to forget them in the future.
