Displaying Translation Entries
The show ip nat translations command displays current translations that reside in
the translation table.
Simple translation entries appear with inside/outside and local/global address
information. Extended entries appear with added protocol and port numbers (or
query IDs).
Using verbose mode additionally provides the time since creation and time since
last use for each translation entry.
