show ip nat translations
show ip nat translations [verbose]
(Optional) Displays additional information for each translation table entry, including how long ago the entry was created and used.
To display active Network Address Translation (NAT) translations, use the show ip nat translations EXEC command.
The following is a sample of output from the show ip nat translations command. Without overloading, two inside hosts are exchanging packets with some number of outside hosts.Router#show ip nat translations Pro Inside global Inside local Outside local Outside global --- 22.214.171.124 192.168.1.95 --- --- --- 126.96.36.199 192.168.1.89 --- --
With overloading, a translation for a DNS transaction is still active, and translations for two Telnet sessions (from two different hosts) are also active. Note that two different inside hosts appear on the outside with a single IP address.Router#show ip nat translations Pro Inside global Inside local Outside local Outside global udp 188.8.131.52:1220 192.168.1.95:1220 184.108.40.206:53 220.127.116.11:53 tcp 18.104.22.168:11012 192.168.1.89:11012 22.214.171.124:23 126.96.36.199:23 tcp 188.8.131.52:1067 192.168.1.95:1067 184.108.40.206:23 220.127.116.11:23

The table describes the significant fields in the display.
Table: show ip nat translationsField Descriptions
Protocol of the port identifying the address
The legitimate IP address (assigned by the NIC or service provider) that represents one or more inside local IP addresses to the outside world.
The IP address assigned to a host on the inside network; probably not a legitimate address assigned by the NIC or service provider.
IP address of an outside host as it appears to the inside network; probably not a legitimate address assigned by the NIC or service provider.
The IP address assigned to a host on the outside network by its owner
How long ago the entry was created (in hours:minutes:seconds).
How long ago the entry was last used (in hours:minutes:seconds).
Indication of the type of translation. Possible flags are:
- extended�Extended translation
- static�Static translation
- destination�Rotary translation
- outside�Outside translation
- timing out�Translation will no longer be used, due to a TCP FIN or RST.
