CCNA Exam Prep Question of the Week

Your router is configured as follows:

interface s0/0/0
ip address 209.165.200.1 255.255.255.0
ip nat outside
interface fa0/0
ip address 10.1.1.1 255.255.255.0
ip nat inside
access-list 1 permit 10.1.1.0 0.0.0.255

Two PCs on the network have addresses 10.1.1.5 and 10.1.1.10.

Which command, when added to the router’s configuration, causes the PCs’ addresses to be translated to the router’s s0/0/0 address?

  1. ip nat inside source list 1 209.165.200.1 overload
  2. ip nat inside source list 1 interface s0/0/0 overload
  3. ip nat inside source list 1 interface s0/0/0
  4. ip nat inside source 1 interface s0/0/0 overload

 

The correct answer is 2.

The “ip nat inside source list 1 interface s0/0/0 overload” command specifies that source addresses permitted by access list 1 will be translated to the address of interface s0/0/0. The “overload” keyword indicates that PAT is used so that one outside address represents many inside addresses, using the port number to distinguish between the translations.
