we are using an ASR 1002 for dynamic NAT (with route maps). I do have a Problem with the usage of the NAT pool it self.
The total NAT Translations for the pool are:
#sh ip nat stat
[Id: 1] route-map natted-host-01 pool nat-pool-01 refcount 136
pool nat-pool-01: netmask 255.255.254.0
start XX.XX.202.0 end XX.XX.203.255
type generic, total addresses 512, allocated 88 (17%), missee 0
If i now look into the NAT translation Table i do get less entries:
#sh ip nat translations filter map-id dynamic 1 total
Total number of translations: 43
Only a deeper look into the QFP gives here the right values:
# sh platform hardware qfp active feature nat data
The ouput count matches the values I get if i isue a sh ip nat stat
My question is how is it handled internally.
We do have a problem too, with raising usage of the pool over the time.
Once allocated Pool entries are not released after a period of time. And no NAT translation occur for that used IP NAT pool Addresses.
The timer on the device are set:
ip nat translation timeout 300
ip nat translation tcp-timeout 900
ip nat translation pptp-timeout 900
ip nat translation udp-timeout 120
ip nat translation routemap-entry-timeout 900
ip nat translation max-entries 750000
Any one a clue or do I have to open a TAC case.
