Explanation of the bold commands:

Ip nat pool-

Defines the pool name of "nat-example" the first public address is

200.200.200.1 and the last address 200.200.200.255. The mask is

255.255.255.0 or /24

Ip nat inside source-

Applies the access-list 1 to the pool "nat-example"

Ip address 200.200.200.1 255.255.255.0 secondary-

Applies the public address to the e0/0 interface as a secondary

address. Since we want to advertise the public address we must

configure the address.

Ip nat inside-

Defines the e0/0 interface as the inside address

Ip nat outside-

Define serial 0 as the outside addresses

Router rip-

Network 200.200.200.0

Because we configures the 200.200.200.0 address as a secondary

address we can advertise it with RIP.

Access-list 1 permit 10.10.10.0 0.0.0.0.255

Permits the private addresses on the 10.10.10.o subnet to be

translated to the public address.

The following is the actual translation taken after the seri10.10.10.1

interface of the router and the workstation 10.10.10.2 performed a

ping of the Serial interface of the ISP’s router.
