CONFIGURATION PAT ( OVERLOADING)

The nice thing about PAT is that these are the only differences between this configuration and the previous dynamic PAT configuraion :

• Our pool of addresses has shrunk to only one ip address.
• we included the overload keyword at the end of our ip nat inside source command.

the one IP address that's in the pool fir us to use is the ip address of the outside interface. this is perfect if you are configuring NAT overload for yourself at home or for a small office that only has one Ip address from your ISP.

DYNAMIC NAT CONFIGURAION

The command ip nat pool test 64.10.75.80 64.10.75.99 netmask 255.255.255.0 creates a pool of addresses that will be distributed to the specific hosts that require global addresses. 

STATIC NAT CONFIGURATION

The ip nat inside source command configures a static translation between the inside local IP address 10.10.10.10 to the outside global IP address 64.10.75.99
