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.

show ip nat translations

Use to display current translations that reside in the NAT translation table.
Field descriptions
- Prot—Protocol (TCP, UDP, ICMP, or GRE) for this translation entry; this field appears only for extended table entries
- Inside local—Inside local IP address for this translation entry; this field also provides the port number, separated by a colon ( : ) for extended entries
- Inside global—Inside global IP address for this translation entry; this field also provides the port number, separated by a colon ( : ) for extended entries
- Outside global—Outside global IP address for this translation entry; this field also provides the port number, separated by a colon ( : ) for extended entries
- Outside local—Outside local IP address for this translation entry; this field also provides the port number, separated by a colon ( : ) for extended entries
- Time since creation—Amount of time elapsed since the translation entry appeared in the translation table
- Time since last use—Amount of time elapsed since the translation entry was used

Example 1

host1# show ip nat translations
show ip nat translations

Prot    Inside local    Inside global    Outside global  Outside local
----    -------------   --------------   --------------  ---------------
GRE     13.1.2.1:*      20.0.0.1:*            ---               ---
ICMP    13.1.2.2:4      20.0.0.2:4            ---               --- 
TCP     13.1.2.3:20     20.0.0.3:50           ---               ---

Note: Because they are not NAPT translations, port numbers for GRE translations appear as asterisks (*).
