How to automatically store or save NAT sessions?

How we can automatically save or store NAT sessions in a syslog or otherwise for future use.

I'm not sure if I understand your requirement. Are you interested in finding out what web sites people have been visiting?

If so you can configure Netflow on your firewall assuming it is running a version of code that supports it.

Alternatively you could configure Netflow on your inside router and then install a Netflow server to analyse the data.

Thanks for your response. Actually we want it to store the NAT sessions for fraud management and in case a Public IP (NAT Global) comes to us, we should be able to reach the real culprit and produce the evidence. These logs are required to be kept for 1 year as per law.
