reading the nat pool

Hi --

We have a 2621 series with a pool of about 100 outside IPs natted to a

When I do a show arp, I'll see an internal addy followed by an outside. Am I correct in assuming that the first 10.x.x.x addy is natted to the following entry which shows an outside addy?

And is there any way to logfile what internal ips are assigned to externals?

Thanks in advance Dave
