Hello Mate, I'm yet to come across how you can achieve this just on a
"standalone" Cisco Box.
However, Syslog Servers could collect historical information for you
(Months/Years worth of info) (Or any other 3rd Party Trap Collection
Tool)
ip nat log translations syslog

ad_c/ch20/ntbmonma.htm#wp1048744
Here is an Except from Cisco DOC DVD:-
Enabling Syslog: Example
The following example shows enabling NAT entries into syslog.
Router(config)# logging on
Router(config)# logging 1.1.1.1
Router(config)# logging trap informational
Router(Config)# ip nat log translations syslog
The format of NAT information logged (for example, for ICMP Ping via NAT
Overload configurations) will be as follows:
Apr 25 11:51:29 [10.0.19.182.204.28] 1: 00:01:13: NAT:Created icmp
135.135.5.2:7 171 12.106.151.30:7171 54.45.54.45:7171
54.45.54.45:7171
Apr 25 11:52:31 [10.0.19.182.204.28] 8: 00:02:15: NAT:Deleted icmp
135.135.5.2:7 172 12.106.151.30:7172 54.45.54.45:7172
54.45.54.45:7172
Many Thanks

Subject: NAT Translation History
Hey Guys,
Please is there a way I can see a history of translations that have
taken place on a NAT router in the past, say 10 hrs?
This is the setup: I have a private network with a bunch of devices
and a NAT router which could translate all internal address to the
outside.
Particularly, I would be looking for a translation to a particular
address.
Thanks
