[c-nsp] Netflow & NAT problem

[news.gmane.org]

But some billing software howtos say, that it is the way (map to 
loopback) to get netflow statistic with NAT, and i do all, as described. 
Also i have Null in DstInt for not NATed IP, and i shure, that it not go 
buy deny ACL, traffic shapers or rate-limit chain. Maybe i need to tune 
that ?

ip flow-cache entries 4094
ip flow-cache timeout inactive 240
ip flow-cache timeout active 45
