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 :
Total active translations: 278405 (0 static, 278405 dynamic; 278460 extended) Outside interfaces: GigabitEthernet0/1.42, GigabitEthernet0/3, GigabitEthernet0/3.9 GigabitEthernet0/3.52 Inside interfaces: GigabitEthernet0/1.45 Hits: 1325770289 Misses: 0 CEF Translated packets: 1248777875, CEF Punted packets: 1186298958 Expired translations: 569696201 Dynamic mappings: -- Inside Source [Id: 1] access-list nat pool nat refcount 278416 pool nat: netmask 255.255.255.0 start **a.b.c.2 end a.b.c.254** type generic, total addresses 253, **allocated 22 (8%)**, misses 0 nat-limit statistics: max entry: max allowed 0, used 0, missed 0
What is algorith of allocating public ip?(where i can read info about it)?
How i can utilizate all of ips?
