Next we need to define a standard access list.
Company(config)#access-list 3 permit 10.30.0.0 0.0.255.255
Based on the previous Network Address Translation labs, what is the
purpose of this
access list?

Now is the time to enter the command to establish dynamic source
translation, identifying the access list defined in the previous step.
However, we are going to add one word to the command to get it to
understand that it should translate multiple internal IP addresses
(local addresses) into just one real IP address (global address).
Company(config)#ip nat inside source list 3 pool net-206 overload
Explain in your own words what the previous command is telling the
router.

We next need to tell the router which interface is connected to
inside network and which interface is connected to the outside.
Company(config)#interface fast ethernet 0/0
Company(config-if)#ip nat inside
Company(config)#interface serial 0/0
Company(config-if)#ip nat outside
Why is it important for the router to know which interface is
connected to the inside network and which is connected to the outside
network?


Now we get to verify the routers address translation.
Company#show ip nat translations
What information did the router respond with?


Company#show ip nat translations verbose
What additional information did the router respond with?


Company#show ip nat statistics
What information did the router respond with?


Hope you didn't forget to add the static route on the ISP router.
Now it is time to test our new configuration. From a workstation on
the inside network attached to the Company router, ping an address on
the outside network (the workstation on the ISP's network).
Company#show ip nat translations
What information did the router respond with?


Company#show ip nat statistics
What information did the router respond with?


From the ISP router ping an address which has a nat listing on
the translation table.
Were you successful?

Now ping an address that is not currently in the routers
translation table.
Were you successful?

Explain the results of the previous two questions.


What is meant by NAT
"overloading"?


Is it possible to be able to configure both static NAT and
overloading NAT on the same router at the same time? If so, explain
how.
