The administrator of a comapny needs to ensure that a web
server in
their network is accessible from the Internet. Since the
network uses private
addressing, this requires an IP-to-registered-address
mapping. The following
command is entered on the router:
router(config)# ip nat inside source static 192.168.2.1
198.18.1.254
After unsuccessful results from a ping to the Internet, the
administrator issues the
show ip nat translations command and the output is blank.
What could be the
problem with the NAT configuration for this mapping?
A. The keyword overload is missing from the command.
B. The administrator needs to define a NAT pool first.
C. An access list must be defined to create static NAT
translations.
D. The interfaces need to be configured for NAT.

The correct answer is (D) - The interface need to be
configured for NAT.
In the above scenario, administrator just configured NAT on
router global configuration mode. He didn't specify the
interface where translation would take place. We need to
specify the interface. For that commands are
Router(config)#interface serial [slot/port]
Router(config-if)# ip nat outside
Router(config)#interface ethernet/fastethernet [slot/port]
Router(config-if)# ip nat inside
