You can see from the output of the show command that the number of hits incremented by
?¬?ve after the NAT statistics were cleared. In a successful ping, the number of hits should
increase by 10. The ?¬?ve ICMP echoes that were sent by the source should be translated, and
the ?¬?ve echo reply packets from the destination should be translated, for a total of 10 hits.
The ?¬?ve missing hits are most likely due to the echo replies not being translated or not being
sent from the destination router.
To determine why the echo reply is not being returned when you issue a ping, check the
default gateway of the destination default gateway router for a route back to the translated
address, as demonstrated in Example 7-5.
The routing table of Router B does not have a route for 172.16.6.14, which is the translated
address. Therefore, the echo replies in response to the ping fail. Once you add this return
route, the ping works.
In Figure 7-7, the network administrator is experiencing the following symptom: Host A
