I have a cisco 7206 vxr with 15.0 ios(c7200p-adventerprisek9-mz.151-3.S0a.bin) .I configured the overloaded nat there. some of confs:

ip nat pool nat a.b.c.2 a.b.c.254 netmask 255.255.255.0

ip nat inside source list nat pool nat overload

Also i do when needed ip nat inside and outside commands.

But the *sh ip nat statistics* gives :

```

type generic, total addresses 253, **allocated 22 (8%)**, misses 0
nat-limit statistics:

```

What is algorith of allocating public ip?(where i can read info about it)?

How i can utilizate all of ips?
