Question : Problem: Cisco router 2600 ... How to create an IP access log?

Hello

I have a Cisco router 2600.

We are using NAT and PAT.  There was an external IP address that I wanted to track down but that IP address was part of the PAT pool.  So there was not a one to one mapping. (Show XLATE).  Is there a way that I can create an IP access log so I could always map the external IP addresses with the internal?

Thanks

The easiest way is to turn on netflow and export to NTOP
http://www.ntop.org
Windows port:

Enable netflow on the router:

Interface Fast 0/0
  ip route-cache flow
!
ip flow-export version 5
